This patch moves doorbell info into adev->gmc structure, to align
with vram info. This will prepare structures for proper ttm management
of the doorbell BAR.
Mhm, this is most likely not a good idea either.
The doorbell isn't managed by the GMC in any way. That are two
completely different things in hw if I'm not completely mistaken.
