mb/google/hatch: Configure reset config to PLTRST for IOAPIC pads
This change configures reset config for all pads routed to IOAPIC as
PLTRST. This is required to ensure that the internal logic of the GPIO
gets reset any time the platform enters S3 or powers off and avoids
any interrupt storms on boot-up.
BUG=b:129933011
TEST=Verified that there are no interrupt storms on boot-up from S5.
