gpu: nvgpu: gv11b: Kernel iface for Dynamic TPC-PG

This patch adds kernel interface for dynamic TPC-PG feature.
User-space needs to send TPC-PG args to kernel via ioctl.

Dynamic TPC-PG feature will allow every context to specify the
number of TPC's it will use to run its workload.
This way, graphics driver can power off non-required TPC's
if a particular context has light to medium workload.
