gpu: nvgpu: move fifo init/deinit code to common

Browse Source 
Add fifo sub-unit to common.fifo to handle init/deinit code
and global support functions.

Split init into:
- nvgpu_channel_setup_sw
- nvgpu_tsg_setup_sw
- nvgpu_fifo_setup_sw
- nvgpu_runlist_setup_sw
- nvgpu_engine_setup_sw
- nvgpu_userd_setup_sw
- nvgpu_pbdma_setup_sw

Split de-init into
- nvgpu_channel_cleanup_sw
- nvgpu_tsg_cleanup_sw
- nvgpu_fifo_cleanup_sw
- nvgpu_runlist_cleanup_sw
- nvgpu_engine_cleanup_sw
- nvgpu_userd_cleanup_sw
- nvgpu_pbdma_cleanup_sw

Added the following HALs
- runlist.length_max
- fifo.init_pbdma_info
- fifo.userd_entry_size

Last 2 HALs should be moved resp. to pbdma and userd sub-units,
when available.

Added vgpu implementation of above hals
- vgpu_runlist_length_max
- vgpu_userd_entry_size
- vgpu_channel_count

Use hals in vgpu_fifo_setup_sw.
