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

Some of the temperature sensors defined in baseboard do not exist in
magolor. With the format the DPTF policies are defined in magolor, all
the entries from the baseboard are included and then the overrides
applied. This causes the non-existent DPTF devices to be exported in
the ACPI table and in turn OS reading invalid temperatures. Fix the
format for DPTF passive and critical policies.

BUG=None
BRANCH=dedede
TEST=Build and boot to OS in magolor. 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.
