mb/google/brya/: Add PEG and initial Nvidia dGPU ASL support

Some brya variants will use a GN20 series Nvidia GPU, which requires
quite a bit of ACPI support code to be written for it. This patch
lands a decent bit of the initial code for it on the brya platform,
including:

1) PEG RTD3 methods
2) DGPU power operations (RTD3 and GCOFF, NVJT _DSM and other Methods)
3) NVOP _DSM method

There will be more support to come later, this is all written to
specifications from the Nvidia Software Design Guide for GN20.
