drivers: pinmux: stm32: Clean up after rework
Following rework of pinmux driver for whole stm32 family, remove call to stm32_get_pin_config which is no more used. Include dt-bindings stm32-pinctrl.h file to ensure coherency between dts files and pinmux driver. Due to change of "port" from enum to a series of define (enum not accepted as dt binding), rework gpio_stm32_config declaration. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>
