06fd513e1e gpu: nvgpu: move common.unit into common.mc
nvgpu.common.unit was just an enum used for passing to nvgpu.common.mc
APIs. So, move the enum into mc.h, and replace the include of unit.h
with mc.h where appropriate. And update the yaml arch.

0ef96e4b1a gpu: nvgpu: correct handling of pbdma rc
nvgpu_rc_pbdma_fault just checks for the id and id_type from struct
nvgpu_pbdma_status_info. These contain invalid values during chsw_load
and chsw_switch. This patch corrects the above bug by checking for the
chsw status and then loading the values for id and type.

The current code reads the pbdma_status info after clearing the
interrupt. Other interrupts can cause enough delay between clearing the
interrupt and pbdma switching the channel leading to invalid channel/tsg
ID. Correct that by reading the pbdma_status info register before
clearing of the pbdma interrupt to correctly read the context
information before the pbdma can switch out the context.

69ef86e627 gpu: nvgpu: move safe code HAL files to fusa
This patch moves all the safe static and non-static functions as well
as its dependencies such as static declared structs into files with
_fusa.c extension. If the original file is left with no functions
remaining then the file is deleted.

Added changes in Makefile, Makefile.sources, nvgpu-hal-new.yaml for
compilation.
