gpu: nvgpu: simplify the runlist update sequence

Browse Source 
Following changes are added here to simplify the overall
sequence.

1) Remove deferred update for runlists. NVS worker thread
shall submit the updated runlist.

2) Moved Runlist mem swap inside update itself. Protect
the swap() and hw_submit() path with a spinlock. This
is temporary till GSP.

3) Enable Control-Fifo mode from nvgpu driver.
