mainboard/google/fizz: Enable support for DPTF

This patch adds the DPTF settings specfic to the mainboard and enables
the CPU and other thermal sensors as participant device for fizz.
It also enables the DPTF flag in the device tree for fizz.

BUG=b:64915426
BRANCH=None
TEST=emerge-fizz coreboot and run DPTF observation tool to make sure
     DPTF is up and running.
