[PATCH v4 0/2] Support Nvidia BlueField-3 GPIO driver and pin controller

[Asmaa Mnebhi]

Support the BlueField-3 SoC GPIO driver for handling interrupts and
providing the option to change the direction and value of a GPIO.
Support the BlueField-3 SoC pin controller driver for allowing a
select number of GPIO pins to be manipulated from userspace or
the kernel.

The gpio-mlxbf3.c driver handles hardware registers and logic
that are different from gpio-mlxbf.c and gpio-mlxbf2.c.
For that reason, we have separate drivers for each generation.

Changes from v3->v4:
gpio-mlxbf3.c:
- Update the Kconfig file so that it is conform with checkpatch
- Remove unncessary headers and add missing header inclusions
- Make irq_chip struct static and const
- Replace generic_handle_irq(irq_find_mapping) with
  generic_handle_domain_irq
- Simplify logic in irq_set_type
- Replace valid_mask with gpio-reserved-ranges
- Cleanup code

pinctrl-mlxbf.c:
- Cleanup code
- Update the Kconfig file so that it is conform with checkpatch
- Remove unncessary headers and add missing header inclusions

  pinctrl: pinctrl-mlxbf: Add pinctrl driver support
