Thomas Fleury 9f233a6ab4 gpu: nvgpu: add setup_sw and cleanup_sw for pbdma
Create common/fifo/pbdma.c and move pbdma common code:
- nvgpu_pbdma_setup_sw
- nvgpu_pbdma_cleanup_sw
- nvgpu_pbdma_find_for_runlist
- nvgpu_pbdma_init_intr_descs

Moved the following HAL from fifo to pbdma
- fifo.find_pbdma_for_runlist -> pbdma.find_for_runlist

Added the following HALs
- fifo.init_pbdma_map
- pbdma.setup_sw
- pbdma.cleanup_sw

Jira NVGPU-2950
