Move the GPIO configuration based on dt_flags previously done in
get_dt ops in the new gpio configure ops.
To avoid glitch on GPIO line, the write in register GPIO_MODER is only
kept in the ops stm32_gpio_set_direction(), called by gpio framework
function gpio_configure() after the call of configure ops, so
we have no more transient GPIO input configuration.
Moreover, this patch allows to correctly apply the dt_flags when
they are modify after the call of stm32_gpio_get_dt(),
for example in drivers regulator fixed and gpio.
