This reverts commit 145eed48de278007f646b908fd70ac59d24ed81a.

Zeno Davatz reported that 145eed48de27 ("fbdev: Remove conflicting devices
on PCI bus") caused a console hang.  The machine was actually still usable
via ssh, etc., but there was no activity on the console.

Reverting 145eed48de27 for the nvidiafb on that system fixed the problem.

Revert 145eed48de27 ("fbdev: Remove conflicting devices on PCI bus") since
we don't know what caused the problem.

Why is the user using nvidiafb?

I don't know, and of course, it really doesn't matter; we shouldn't
regress a user's experience, and there's no hint to the user of where
to look for a resolution.

Thanks for working out a better fix!
