    drm/nouveau/fb: remove ram oclass argument from base fb constructor

Introduced a unfortunate regression by using nv10 ram oclass for nv1a
hardware, causing corruption and eventually system lockup.

Commit ea7dce90 ("drm/nv50/gr: print mpc trap name when it's not an mp
trap") added an nv_error call that was missing the priv parameter. This
causes GPFs if the error is ever hit.

Since commit 0fa9061a ("drm/nouveau/mc: handle irq-related setup
ourselves"), drm_device->irq_enabled remained unset. This is needed in
order to properly wait for a vblank event in the generic drm code.

If either idling channels or suspending the fence were to fail, the
display would never be resumed. Also if a client fails, resume the fence
(not functionally important, but it would potentially leak memory).

The DRM uses the adjusted mode to calculate constants for vblank
timestamping.  Our encoder mode_fixup (usually) replaces this data
with our backend mode information, which doesn't have the needed
data filled in already.

Still essentially a struct of magic values with magic names and unknown
purposes.  But, we will shortly need to be able to mix and match bits of
the previous and next configurations to do a transition reclock, as such,
we can no longer directly use the vbios data with any ease.

This is probably nicer anyway in the long run, for a few reasons.
