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.
