Rather than always using handle_simple_irq() as the gpio_irq_chip
handler, set a more appropriate handler based on the IRQ trigger type
requested. This is important for level triggered interrupts which need
to be masked during handling. Also, fix the interrupt acknowledge so
that it clears only one interrupt instead of all interrupts which are
currently active. Finally there is no need to clear the interrupt during
the interrupt handler, since the edge-triggered handler will do that for
us.

This change drops the override in `amd_gpio_irq_set_type()` that
ignores the IRQ trigger type settings from the caller. The device
driver (caller) is in a better position to identify the right trigger
type for the device based on the usage as well as the information
exposed by the BIOS. There are instances where the device driver might
want to configure the trigger type differently in different modes. An
example of this is gpio-keys driver which configures IRQ type as
trigger on both edges (to identify assert and deassert events) when in
S0 and reconfigures the trigger type using the information provided by
the BIOS when going into suspend to ensure that the wake happens on
the required edge.
This override in `amd_gpio_irq_set_type()` prevents the caller from
being able to reconfigure trigger type once it is set either based on
ACPI information or the type used by the first caller for IRQ on a
given GPIO line.
Without this change, pen-insert gpio key (used by garaged stylus on a
Chromebook) works fine in S0 (i.e. insert and eject events are
correctly identified), however, BIOS configuration for wake on only
pen eject i.e. only-rising edge or only-falling edge is not honored.
With this change, it was verified that pen-insert gpio key behavior is
correct in both S0 and for wakeup from S3.

The PAT1 register contains information about the IRQ type (edge/level)
for input GPIOs with IRQ enabled, and the direction for non-IRQ GPIOs.
So it makes sense to read it only if the GPIO has no interrupt
configured, otherwise input GPIOs configured for level IRQs are
misdetected as output GPIOs.

Ingenic SoCs don't natively support registering an interrupt for both
rising and falling edges. This has to be emulated in software.
Until now, this was emulated by switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING according to the level of
the GPIO. While this worked most of the time, when used with GPIOs that
need debouncing, some events would be lost. For instance, between the
time a falling-edge interrupt happens and the interrupt handler
configures the hardware for rising-edge, the level of the pin may have
already risen, and the rising-edge event is lost.
To address that issue, instead of switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING, we now switch back and
forth between IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH. Since we
always switch in the interrupt handler, they actually permit to detect
level changes. In the example above, if the pin level rises before
switching the IRQ type from IRQ_TYPE_LEVEL_LOW to IRQ_TYPE_LEVEL_HIGH,
a new interrupt will raise as soon as the handler exits, and the
rising-edge event will be properly detected.

If a GPIO bank has greater than 16 pins, PAD_DS_REG is split into two
or more registers. However, when register and bit were calculated, the
first register defined in the bank was used, and the bit was calculated
based on the first pin. This causes problems in setting the driving
strength.
The following method was used to solve this problem:
A bit is calculated first using predefined strides. Then, If the bit is
32 or more, the register is changed by the quotient of the bit divided
by 32. And the bit is set to the remainder.

* Fix output pin value handling on Intel Baytrail
The following is an automated git shortlog grouped by driver:
baytrail:
- Fix pin being driven low for a while on gpiod_get(..., GPIOD_OUT_HIGH)
The pins on the Bay Trail SoC have separate input-buffer and output-buffer
enable bits and a read of the level bit of the value register will always
return the value from the input-buffer.
The BIOS of a device may configure a pin in output-only mode, only enabling
the output buffer, and write 1 to the level bit to drive the pin high.
This 1 written to the level bit will be stored inside the data-latch of the
output buffer.
But a subsequent read of the value register will return 0 for the level bit
because the input-buffer is disabled. This causes a read-modify-write as
done by byt_gpio_set_direction() to write 0 to the level bit, driving the
pin low!
Before this commit byt_gpio_direction_output() relied on
pinctrl_gpio_direction_output() to set the direction, followed by a call
to byt_gpio_set() to apply the selected value. This causes the pin to
go low between the pinctrl_gpio_direction_output() and byt_gpio_set()
calls.
Change byt_gpio_direction_output() to directly make the register
modifications itself instead. Replacing the 2 subsequent writes to the
value register with a single write.
Note that the pinctrl code does not keep track internally of the direction,
so not going through pinctrl_gpio_direction_output() is not an issue.
This issue was noticed on a Trekstor SurfTab Twin 10.1. When the panel is
already on at boot (no external monitor connected), then the i915 driver
does a gpiod_get(..., GPIOD_OUT_HIGH) for the panel-enable GPIO. The
temporarily going low of that GPIO was causing the panel to reset itself
after which it would not show an image until it was turned off and back on
again (until a full modeset was done on it). This commit fixes this.
This commit also updates the byt_gpio_direction_input() to use direct
register accesses instead of going through pinctrl_gpio_direction_input(),
to keep it consistent with byt_gpio_direction_output().
Note for backporting, this commit depends on:

There are plenty of places where we call
readl(chv_padreg(pctrl, offset, ...));
Replace them with newly introduced chv_readl() helper
chv_readl(pctrl, offset, ...);

uart0_pins is defined as:
static const unsigned uart0_pins[] = {135, 136, 137, 138, 139};
which npins is wronly specified as 9 later
{
.name = "uart0",
.pins = uart0_pins,
.npins = 9,
},
npins should be 5 instead of 9 according to the definition.
