Change the settings to support pinctrl on the GD32VF103.
- Split soc/arm/gigadevice/common/pinctrl_soc.h
and put it into include/dt-bindings.
- Leave some definitions that can't handle with device tree compiler
in pinctrl_soc.h.
- Remove dependency to SOC_FAMILY_GD32 because always enabled it
if GD32_HAS_AF(IO)_PINMAX was selected.

Make gpio32_stm32_configure use runtime PM API (so that it can be used
externally without further effort). The raw version of the function (no
PM put/get) has been introduced for internal use.

The PM runtime API (get/put) provides an inline implementation when not
built-in. Such implementation always returns 1, so it is safe to not
guard PM runtime calls and check for < 0.

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.

Add initial version for STM32 pinctrl driver. Driver has been written
re-using many of the already existing parts in
drivers/pinmux/pinmux_stm32.c.

Add support for dynamic pin control, that is, allow to change device pin
configuration at runtime. Because no device de-initialization is
available yet, this API has limited usage options, e.g. modify pin
configuration at early boot stage (before device driver is initialized)
