…x devices. RW61x devices loses peripheral context when entering into PowerMode 3, so when exiting form this power mode, it is necesary to restore all context. This is a preliminary solution until who is responsible to restore this context and to know the zephyr's contract for Power Management. Signed-off-by: Missael Maciel <[email protected]>

THIS IS A PRELIMINARY SOLUTION TO HELP CONTINUE THE DRIVER'S SUPPORT FOR POWER MANAGEMENT ON RW61x DEVICES
On RW61x devices, when entering in PM3, all peripheral lose their state/context. After exiting from this power mode, that context needs to be restored. This PR saves the GPIOs registers before entering to PM3 and restores the registers after exiting PM3, this helps the application recover all GPIOs configurations when returning from this power mode.
