[0/7] fix PCI AER issues

The first 3 patches fix the actual PCI AER issue by moving
the nbio HDP remap callback to the GMC code where it is used.
Lijo prefered calling the common hw init early, but that
ran into additional problems on vega systems because it
depends on doorbell apertures having been set up for IH
and SDMA so we run into an ordering problem there.  We
already call the other NBIO callbacks as well as the HDP
callbacks from other IPs when they are needed so it seems
logical to me to move the HDP remap into GMC since it's
mainly used as part of memory management anyway.

The 4th patch just fixes up nbio 7.7 for consistency.

The next 2 patches are optional, but make the code more
consistent with that we do for other IPs.  See those
patches for some additional comments about the ordering
with respect to the doorbell setup.  I didn't notice
any problems in my testing and the VCN doorbell setup
already breaks that rule, so I'm not sure if it's actually
necesary or not.

Finally the last patch enabled early common IP init to happen
before GMC.  It's not strictly necessary with the first 3
patches, but there may be value in it to have the common stuff
enabled before GMC.
