pinctrl: amd: disable and mask interrupts on probe



[ Upstream commit 4e5a04be88fe335ad5331f4f8c17f4ebd357e065 ]

Some systems such as the Microsoft Surface Laptop 4 leave interrupts
enabled and configured for use in sleep states on boot, which cause
unexpected behaviour such as spurious wakes and failed resumes in
s2idle states.

As interrupts should not be enabled until they are claimed and
explicitly enabled, disabling any interrupts mistakenly left enabled by
firmware should be safe.
