Add initial support for nRF pin controller driver. The implementation in
this patch does not yet support any peripheral. Only states
representation and basic driver functionality is introduced.
Note:
The nrf_pin_configure function has been marked as __unused since it may
not be used in certain scenarios until all peripherals are supported by
the pinctrl driver. For example, if only UART/E is supported but the
board does not enable UART, the function will never get called. However,
that board will likely have other peripherals that will gain support in
the future.
Thanks to Marti Bolivar for bindings documentation.
