On SoC stm32mp257, GPIO supports security and isolation compliant
with the Resource Isolation Framework (RIF). Each GPIO line can be
assigned to different security and compartment domains.
Add the generic code to handle the RIF configuration set by the
secure world and initialize the GPIO valid mask accordingly.
Enable the RIF support for stm32mp257.

The driver for stm32mp257 is missing the suspend callback in
struct dev_pm_ops.
Add the callback, using the common stm32_pinctrl_suspend()
function.
