pinctrl: amd: Mask non-wake source pins with interrupt enabled at suspend
If a pin isn't marked as a wake source processing any interrupts is
just going to destroy battery life. The APU may wake up from a hardware
sleep state to process the interrupt but not return control to the OS.
Mask interrupt for all non-wake source pins at suspend. They'll be
re-enabled at resume.
