Now that it's a normally kmalloce buffer we can use the usual cleanup
paths. The upside here is that if we get the refcounting wrong will be
able to catch it, since the drm core will complain about leftover
framebuffers and kref about underflows.
v2: Kill intel_framebuffer_fini - no longer needed now that we
refcount all fbs properly and only confusing.
v3: We actually still need to call unregister_private to remove the fb
from the idr and drop the idr reference - the final unref doesn't do
that. So much for remembering my own fb liftime rules. Reported by
Imre Deak.

Allocate this struct instead, so we can re-use another allocated
elsewhere if needed.

Because whatever.*

unresolved resgressions, but I didn't really get a vote.

Multiple definitions show up multiple times in modinfo output.
There's already an identical one in i915_drv.c along with other MODULE_*
definitions, so drop the lone one in intel_fbdev.c.

This should just be a debug. Add another debug msg to the inherit path
while we're at it.

If we use a stolen buffer, our probe callback shouldn't allocate a new
buffer; we should re-use the one from the BIOS instead if possible.

Use the nice Kernel macro, it makes the code much more readable.

This file is all about the legacy fbdev support. If we want to extract
framebuffer functions, we better put those into a separate file.
Also rename functions accordingly, only two have used the intel_fb_
prefix anyway.
