84a24c9593 gpu: nvgpu: Remove TPC powergate from safety build
- Remove non-safe TPC powergate feature from the safety
  build by introducing a new flag:
  CONFIG_NVGPU_TPC_POWERGATE

- Move nvgpu_init_power_gate_gr() under same compile time flag.
  and move HAL function gr_gv11b_powergate_tpc() to tpc_gv11b.c

- Also, remove the negative test scenario and
  usage of tpc_powergate from unit tests

2916a2067d gpu: nvgpu: Use TPC_PG_MASK to powergate the TPC
- In GV11B, read fuse_status_opt_tpc_gpc register
  to read which TPCs are floorswept.
- The driver will also read sysfs node: tpc_pg_mask
- Based on these two values "can_tpc_powergate" will
  be set to true or false and mask will be used to write to
  fuse_ctrl_opt_tpc_gpc register to powergate the TPC.
- can_tpc_powergate = true indicates that the mask value
  sent from userspace is valid and can be used to power gate
  the desired TPC
- can_tpc_powergate = false indicates that the mask value
  sent from userspace is not valid and cannot  be used to
  power gate the desired TPC.
