pinctrl: amd: Disable and mask interrupts on resume

commit b26cd932 upstream.

This fixes a similar problem to the one observed in:
commit 4e5a04be ("pinctrl: amd: disable and mask interrupts on probe").

On some systems, during suspend/resume cycle firmware leaves
an interrupt enabled on a pin that is not used by the kernel.
This confuses the AMD pinctrl driver and causes spurious interrupts.

The driver already has logic to detect if a pin is used by the kernel.
Leverage it to re-initialize interrupt fields of a pin only if it's not
used by us.
