gpu: nvgpu: Move programming of host registers to fifo
Move code that touches host registers and instance block to fifo HAL.
This involves adding HAL ops for the fifo HAL functions that get
called from outside fifo. This clears responsibility of channel by
leaving it only managing channels in software and push buffers.
channel had member ramfc defined, but it was not used, to remove it.
pbdma_acquire_val consisted both of channel logic and hardware
programming. The channel logic was moved to the caller and only
hardware programming was moved.
