Deepak Nibade 84a37954fb gpu: nvgpu: keep runlist submit lock only for submit registers ...

We right now acquire rulist_submit_mutex to submit runlist and also
to wait for submit completion

But locking is only needed to atomically configure the runlist submit
registers, hence move the locking to inside of
gk20a_fifo_runlist_hw_submit() where we program the registers

Also convert the mutex to spinlock at the same time

Note that similar locking is not required for
tu104_fifo_runlist_hw_submit() since the runlist submit registers
are per-runlist beginning Turing
