gumboz: add thermal protect parameter

This patch add thermal protect parameter for gumboz(same as dirinboz):
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.
