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.
