nvgpu: gpu: Support multiple tpc-pg masks.
- TPC powergating should be done before
calling gk20a_enable_gr_hw.
gk20a_enable_gr_hw() issues a GR engine reset.
Without this fix, enabling 1 TPC from each PES
causes ctxsw timeout error while running GFX Benchmark.
- Adds valid tpc-pg mask for 1/2/3/4 active TPC configs.
TPC Config - TPC-MASK
4 TPC configuration - 0x0
3 TPC configuration - 0x1/0x2/0x4/0x8
2 TPC configuration - 0x5/0x9/0x6/0xa
- We should not write to gr_fe_tpc_pesmask_r()
as part of TPC-PG sequence. This register is for
debug purpose only.
