cheza: Add more power signals for informative purpose
No power sequence logic is chanaged. Add PS_HOLD, PMIC_FAULT_L, and
POWER_GOOD (the real one, not AP_RST_L) as power signals. If their
states change, the EC console will show it and the timestamp.
BRANCH=none
BUG=b:78455067
TEST=Ran "gpioset SWITCHCAP_ON_L 0" and showed the signals changed:
7 signal changes:
750.164712 +0.000000 AP_RST_L => 0
