Based on introduction of plain GPIO configurations in STM32 pinctrl
bindings, update STM32 pinctrl/gpio drivers to make this functionality
available.

Before updating stm32 pinctrl/gpio drivers to support plain GPIO
feature, rework pin configuration functions headers to provide
more clarity on the arguments and the information they convey:
- pin configuration
- pin function

- Move SWJ_CFG initialization into pinctrl.
- Don't disable the AFIO clock after SWJ_CFG
initialization.
- Apply '111' to the SWJ_CFG bits upon remap
application, that fixes the remap usage.

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