[PATCH v2] i.MX51 Framebuffer support

[Sascha Hauer]

The following series adds i.MX51 framebuffer support based on the IPUv3. It
is not perfect but I decided it is good enough to open it for a wider audience
and collect first reviews. I tested this on a babbage board using both outputs
(VGA/DVI) with different resolutions up to 1680x1050 and different colour depths.
I also tested it on one custom board using a fixed display setting.

Changes since v1:

- added full overlay support for i.MX51
- more data structures protection
- IPU clock now gets disabled when unused
- many minor cleanups due to comments received from the first round.


The following changes since commit 28a4f908acb342350b9ecbfcdf0a999cb83e05aa:
