cheza: Disable interrupts which are floating when switchcap off
The power signals, AP_RST_L and PMIC_FAULT_L, are floating when
switchcap off. Disable their interrupts. The PS_HOLD and POWER_GOOD
should be OK as they have pull-down.
BRANCH=none
BUG=b:78455067
TEST=Checked "power on", "power off", "apshutdown", and
"apreset".
