mainboard/google/chell: Set TCC activation offset to 10 degree C
With the default TCC activation offset value as 0 and Tjmax
temperature value as 100 degree C, Pcode firmware starts taking
prochot action at 100 degree C [Tjmax-Offset].
But before Pcode firmware starts prochot action at 100 degree C,
device is getting shutdown at 99 degree C due to DPTF critical
CPU temperature.
This patch sets TCC activation offset value to 10 degree C for
thermal throttle action to prevent this kind of shutdown.
BUG=chrome-os-partner:59397
BRANCH=None.
TEST=Built, booted on skylake and verified target offset value.
