The stm32 gpio driver private data are not needed in arch include files, they are not used by code except for stm32 gpio and pincontrol drivers, using the same IP; the defines for this IP is moved in a new file "stm32_gpio_priv.h" in driver/gpio. This patch avoids to have duplicated file gpio.h for each SOC in MPU directory mach-stm32mp and in each MCU directory arch-stm32* and allows to remove CONFIG_GPIO_EXTRA_HEADER for all STM32.
