dirinboz: update thermal protect parameter
This patch update thermal protect parameter as below:
All trigger/release by charger thermistor,
Charging current 0.5A: Trigger > 58’C ; Release < 57’C
CPU PROCHOT: Trigger > 63’C ; Release < 62’C
Set USB-C0 port to 1.5A: Trigger > 63’C ; Release < 62’C
BUG=b:181803301
BRANCH=zork
TEST=verify EC behavior intended when trigger/
release thermal protection.
