Convert drivers to use grp member embedded in struct group_desc,
because other members will be removed to avoid duplication and
desynchronisation of the generic pin group description.

The pins are allocated from the heap, but in order to pass
them as constant object, we need to use non-constant pointer.
Achieve this by using a temporary variable.

of_property_count_u32_elems() might return an error code in some cases.
It's naturally better to assign what it's returned to the err variable
and supply the real code to the upper layer(s). Besides that, it's a
common practice to avoid assignments for the data in cases when we know
that the error condition happened. Refactor the code accordingly.

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

Intel Lightning Mountain SoC has a pinmux controller & GPIO controller IP which
controls pin multiplexing & configuration including GPIO functions selection &
GPIO attributes configuration.
This IP is not based on & does not have anything in common with Chassis
specification. The pinctrl drivers under pinctrl/intel/* are all based upon
Chassis spec compliant pinctrl IPs. So this driver doesn't fit & can not use
pinctrl framework under pinctrl/intel/* and it requires a separate new driver.
Add a new GPIO & pin control framework based driver for this IP.
