Currently the vGPU engine management rewrites a lot of the common
device agnostic engine management code.
With the new top HAL parsing one device at a time, it is now more
easily possible to tie the vGPU into the new common device framework
by implementing the top HAL but with the vGPU engine list backend.
This lets the vGPU inherit all the common engine and device
management code. By doing so the vGPU HAL need only implement a
trivial and simple HAL.
This also gets us a step closer to merging all of the CE init
code: logically it just iterates through all CE engines whatever
they may be. The only reason this differs between chips is because
of the swap from CE0-2 to LCEs in the Pascal generation. This could
be abstracted by the unit code easily enough.
Also, the pbdma_id for each engine has to be added to the device
struct. Eventually this was going to happen anyway, since the
device struct will soon replace the nvgpu_engine_info struct.
It's a little bit of an abuse but might be worth it long term. If
not, it should not be difficult to replace uses of dev->pbdma_id
with a proper lookup of PBDMA ID based on the device info.

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.

MISRA Rule-17.7 requires the return value of all functions to be
used. Fix is either to use the return value or change the function
to return void. This patch contains fixes for all 17.7 violations
in the following units:
- nvgpu.common.hal.fifo.runlist
- nvgpu.common.hal.fifo.fifo
