gpio: max7360: Add MAX7360 gpio support
Add driver for Maxim Integrated MAX7360 GPIO/GPO controller.
Two sets of GPIOs are provided by the device:
- Up to 8 GPIOs, shared with the PWM and rotary encoder functionalities.
These GPIOs also provide interrupts on input changes.
- Up to 6 GPOs, on unused keypad columns pins.
