Subject: [PATCH] pinctrl: max77620: add OF dependency

Drivers using pinconf_generic_params tables cannot be built with
CONFIG_OF disabled:

drivers/pinctrl/pinctrl-max77620.c:53:44: error: array type has incomplete element type ‘struct pinconf_generic_params’
drivers/pinctrl/pinctrl-max77620.c:55:3: error: field name not in record or union initializer
drivers/pinctrl/pinctrl-max77620.c:55:3: note: (near initialization for ‘max77620_cfg_params’)
drivers/pinctrl/pinctrl-max77620.c:56:3: error: field name not in record or union initializer

This adds a dependency for max77620 to disallow that configuration.

Alternatively, we could rework the pinctrl infrastructure to make the
configuration valid for compile-testing.
