Add GPIO driver for these pins to control via GPIO APIs.

PS, please add these optional features:

+       mgpio->gpio_chip.direction_input = max77620_gpio_dir_input;
+       mgpio->gpio_chip.direction_output = max77620_gpio_dir_output;

Any chance you could send a patch to add a .get_direction() callback?

Sure, I will send the patch for this and also for the set_single_ended().

I will post the patch on top of this patch as a new patch as this is 
already applied in your tree.
Later on, it can be squashed or added as new patch.
