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.
