mb/google/dedede/var/cret: Fix DPTF passive and critical policies

TSR2 thermal sensor doesn't define in cret. Fix DPTF passive and
critical policies for getting negative temperatures in OS.

BUG=b:195868075
BRANCH=dedede
TEST=Build and boot to OS in cret. Ensure that the DPTF entries look
correct in both static.c and SSDT tables i.e. passive and critical
policies for applicable devices only are present.
