soc/intel/common: Add support to clear GPI IS & IE registers
Add support to reset the GPI Interrupt Status & Enable registers so that
the system does not experience any interrupt storm from a GPI when it
comes out of one of the sleep states.
BUG=b:130593883
BRANCH=None
TEST=Ensure that the Interrupt status & enable registers are reset
during the boot up. Ensure that the system boots fine to ChromeOS.
