2022-05-20	mb/google/brya/acpi: Add support for NBCI _DSM subfunction	Tim Wawrzynczak
	The Nvidia GPU supports another function named NBCI (NoteBook Common Interface), which has some subfunctions which are required for the Nvidia kernel driver to consume. The specification for this function comes from the Nvidia GN20 Software Design Guide.

2022-05-20	mb/google/brya: Add PEG and initial Nvidia dGPU ASL support	Tim Wawrzynczak
	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.
