gpu: nvgpu: tpc powergating through sysfs
- adds static tpc-powergating through sysfs.
- active tpc count will remain till the GPU/systems is not booted again.
- tpc_pg_mask can be written only after GPU probe finishes and
GPU boot is triggered.
Note:
To be able to use this feature, we need to change boot/init
scripts of the OS(used with nvgpu driver) to write to sysfs nodes before
posting discover image size query to FECS.
