mb/google/puff: Convert ASL file to new DPTF dt impl

This patch converts the current DPTF policies from static ASL files into
the new SSDT-based DPTF implementation. All settings are intended to be
copied exactly.

BUG=b:158986928
BRANCH=puff
TEST=duffy boots and dumped SSDT table for quick check.
