intel/apollolake: Update gnvs for dptf
This patch updates dptf variable in gnvs based on device
configuration by reading the device tree structure.
BUG=chrome-os-partner:53096
TEST=Verify that the thermal zones are enumerated
under /sys/class/thermal in Amenia and Reef board.
Navigate to /sys/class/thermal, and verify that a
thermal zone of type TCPU exists there.
