Antony Clince Alex 62d6f753d2 gpu: nvgpu: add support for PES, ROP floorsweeping
Volta+ chips supports PES floorsweeping and Ampere+(iGPU) chips supports
ROP floorsweeping. At present, the driver isn't aware of PES, ROP
floorsweeping, make the driver PES, ROP floorsweeping aware by introducing the
following fields in nvgpu_gr_config:
- gpc_(rop/pes)_mask: Contains the bit mask of non FSed ROP/PES units per GPC.
- gpc_(rop/pes)_logical_id_map: Translates per GPC ROP/PES physical id to
  logical id.

Introduce the following HAL functions to read PES/ROP FS data:
- gops_fuse.fuse_status_opt_(pes/rop)_gpc: This fuction gets the FS
  config from the fuse.
- gops_top.get_max_(pes/rop)_per_gpc: Gets the maximum number of PES/ROP
  units that can be present in a GPC.

In addition, introduce the enabled flag NVGPU_SUPPORT_PES_FS to identify chips
which support PES floorsweeping, piggyback on NVGPU_SUPPORT_ROP_IN_GPC
enabled flag to identify ROP floorsweeping.
