pinctrl: amd: Add an LPS0 check() callback

During suspend the pinctrl_amd driver disables the interrupts for
any GPIOs that are not marked as wake sources.

This however does not prevent them from changing the wake status
bit during suspend, it just stops the system from waking.

If the system wakes from hardware sleep for another reason (such
as plugging in the AC adapter) this wake bits might be active.

This could potentially cause problems with going back to hardware
sleep.  Add an extra debugging message when PM debugging is enabled
to help identify if this is happening.
