pinctrl: amd: Disable and mask interrupts on resume
This fixes a similar problem to the one observed in:
commit 4e5a04be88fe ("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.
