[v6,0/2] Support Nvidia BlueField-3 GPIO driver and pin controller

Message

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 v5->v6:
- fix some nits in gpio-mlxbf3 and pinctrl-mlxbf3
- add err.h and io.h header files

  gpio: mlxbf3: Add gpio driver support
  pinctrl: mlxbf: Add pinctrl driver support
