Currently, the i2c-hid driver does not call the suspend, resume, and
reset_resume callbacks in the hid_driver struct when those events occur.
This means that HID drivers for i2c-hid devices will not be able to execute
commands which may be needed during suspend or resume. One example is when a
touchpad using the hid-multitouch driver gets reset by i2c-hid coming out of
resume. Since the reset_resume callback never gets called the device is never
put back into the correct input mode. This patch calls the suspend and resume
callbacks and tries to duplicate the functionality of the usb-hid driver.

Userspace tools may use hidraw to perform operations on the device from userspace while
hid-rmi is bound to the device. This can cause hid-rmi to print error messages when its
->raw_event() callback gets called as the reports pass through the HID stack. In this case
receiving responses which were not initiated by hid-rmi is not actually an error so the resulting
error messages are incorrect and misleading. This patch changes the log messages to debug so
that the messages can be turned on in the event that there is a problem and there is not
a userspace tool running.

This solves a bug with the wireless receiver:
- at plug, the wireless receiver does not know which Wacom device it is
connected to, so it does not actually creates all the LEDs
- when the tablet connects, wacom->wacom_wac.features.type is set to the
proper device so that wacom_wac can understand the packets
- when the receiver is unplugged, it detects that a LED should have been
created (based on wacom->wacom_wac.features.type) and tries to remove
it: crash when removing the sysfs group.
Side effect, we can now safely call several times wacom_destroy_leds().

All USB Wacom tablets are actually HID devices.
For historical reasons, they are handled as plain USB devices.
The current code makes more and more reference to the HID subsystem
like implementing its own HID report descriptor parser to handle new
devices.
From the user point of view, we can transparently switch from this state
to a driver handled in the HID subsystem and clean up a lot of USB specific
code in the wacom.ko driver.
The other benefit once the USB dependecies have been removed is that we can
use a tool like uhid to make regression tests and allow further cleanup or
new implementations without risking breaking current behaviors.
To match the current handling of devices in wacom_wac.c, we rely on the
hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when
it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the
device is plain HID. There is thus a one to one matching between the list
of supported devices before and after the switch from USB to HID.

The basic API of rc-core used to be:
dev = rc_allocate_device();
dev->x = a;
dev->y = b;
dev->z = c;
rc_register_device();
which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:
dev = rc_allocate_device();
dev->x = a;
rc_set_allowed_protocols(dev, RC_BIT_X);
dev->z = c;
rc_register_device();
There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

CP2112 does not offer an atomic method to set both gpio
direction and value.
Also it does not permit to set gpio value before putting
gpio in output. In fact, accordingly to Silicon Labs
AN495, Rev. 0.2, cpt. 4.4, the HID report to set gpio
values "does not affect any pins that are not configured
as outputs".
This is confirmed on evaluation board CP2112-EK.
With current driver, after execute:
echo in > /sys/class/gpio/gpio248/direction
echo low > /sys/class/gpio/gpio248/direction
gpio output is still high. Only after a following
echo low > /sys/class/gpio/gpio248/direction
gpio output gets low.
Fix driver by changing order of operations; first set
direction then set value.
The drawback of this new sequence is that we can have
a pulse on gpio pin when direction is changed from
input to output-low, but this cannot be avoided on
current CP2112.

Simplify the logic of overriding the Sixaxis HID descriptor, this will
make it easier to amend the descriptor in future commits.
The current code does this:
if (original sixaxis via USB or BT)
fixup only a part of the descriptor
else if (sixaxis compatible controller)
override the _whole_ descriptor
but the end result is exactly the same, except for the trailing zero in
the case of original BT controllers.
So let's just regularize the process, and always override the HID
descriptor.
Always overriding the descriptor changes the current semantic a little
bit, before this change the BT descriptor still had the trailing zero
byte, while now it is exactly the same as the descriptor of the
controller via USB, but that does not affect proper operation of the
device.
Note that overriding the whole descriptor for original devices is not
strictly necessary for now, but it simplifies the code and in the future
the report descriptor will be patched further and keys will be remapped,
so it's handy to have only one place to patch.
