held across any operations that modify mode lists, crtc config, output
config, etc. It should be taken at high level entry points (currently just
initial config and user IOCTL).
Seems to work ok on my system, but needs more testing (with lockdep) and
review from some fresh eyes.

Lots of changes to merge with alanh's latest stuff:
o fix use of fb->pitch now that it has the right value
o add new helper for finding the CRTC given an FB
o fix new fb_probe/fb_remove functions to take a CRTC
o fixup callers of new FB routines
o port drm_fb changes to intel_fb
o check for errors after creating fb buffer object
o go back to using cfb_imageblit since the accel stubs aren't ready
places).
Add new FB hooks to the drm driver structure and make i915 use them for an
Intel specific FB driver. This will allow acceleration and better handling
of the command stream.
Change from DIRECTCOLOR to TRUECOLOR, and enable
support for PSEUDOCOLOR. DIRECTCOLOR support needs more work.
Add the ability to change the mode on the fbdev device.
Support depth 8, 15, 16 and 24 (and 32).
Add a /dev/fbX device per CRTC, but there's some code which
doesn't allocate the fbX device unless the output is actually
enabled. Read the code on this as it impacts the fbcon map flags.
Pick CRTC's based on the available outputs. More work could
be done here to match modes, so cloning could be achieved on
outputs. This fits more inline with what the X code does.
