Revert "mb/google/rex/var/screebo: Reduce TCC from 90°C to 80°C"

This reverts commit 449c6d981c.

Reason for revert: (EVT board build does not exhibit shutdown followed
by warm reboot)

This commit reverts the workaround that limits the TCC activation
temperature. The original issue that was reported (shutdown followed
by warm reboot) was not seen in the EVT board build, so this change is
likely unnecessary.
