Save and restore during PM suspend/resume sequences the state of the
consumed GPIOs.
Consumers are expected to get their GPIOs using the DT resources hence
register a PM handle when the GPIO is requested (stm32_gpio_get_dt()) so
that the dependency order established during drivers initialization is
satisfied during PM suspend and resume sequences. PM handle is
unregistered when consumer releases the GPIO which requires the handles
to be referenced in a list so that we can find it back.
