mb/google/dedede/var/boten: Fix DPTF passive and critical policies
Thermal sensor2 defined in baseboard do not exist in boten. With the format the DPTF policies are defined in boten, 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 boten. 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.
