Deepak Nibade 8b665ac6b2 gpu: nvgpu: move clean up of jobs to separate worker ...

We currently clean up the jobs in gk20a_channel_update()
which is called from nvhost worker thread

Instead of doing this, schedule another delayed worker thread
clean_up_work to clean up the jobs (with delay of 1 jiffies)

Keep update_gp_get() in channel_update() and not in
delayed worker since this will help in better book
keeping of gp_get

Also, this scheduling will help delay job clean-up so
that more number of jobs are batched for clean up
and hence less time is consumed by worker
