gpu: nvgpu: Use gv11b_css_hw_set_handled_snapshots for GV11B

The value of NV_PERF_PMASYS_MEM_BUMP is different for Volta
and NVGPU_IOCTL_CHANNEL_CYCLE_STATS_SNAPSHOT_CMD_FLUSH did not
have correct behavior on GV11B due to that.
The patch adds an instance of css_hw_set_handled_snapshots
for Volta to fix that.
The patch also renames css_hw_set_handled_snapshots
to gk20a_css_hw_set_handled_snapshots to make it more clear
that the function is arch dependent.
