gpu: nvgpu: gk20a: add submit_lock
Add submit mutex lock to avoid race conditions between submitting
a job, removing a job and submitting WFI
With this lock make below operations atomic :
during submit_gpfifo() -
1. getting new syncpt
2. inserting syncpt increment
3. submitting gpfifo
4. setting job completion interrupt
during submit_wfi() -
1. getting new syncpt
2. inserting syncpt increment when idle
during channel_update() -
1. checking the submit job completion
2. freeing the job if it is completed
