gpu: nvgpu: Get rid of legacy gpfifo type

Browse Source 
Get rid of the duplicate gpfifo struct to emphasize the fact that
nvgpu_gpfifo is the only memory layout for gpfifo entries that works.
This is the same layout that HW uses.

Also, add a local pointer to the gpfifo memory in
gk20a_submit_channel_gpfifo to get rid of repeated typecasts.
