The requested pixelformat is being propagated from the capture to the
tpg in the sensor.
This was a bad design choice, as we start having the following issues:
* We set a pixelformat in the capture;
* We set matching media bus formats in the subdevices pads;
* Link validate looks fine (sizes matches, media bus formats matches);
* Issue: if some of the subdevice doesn't know how to generate the
requested pixelformat in the capture, then stream_on fails. This is bad
because capture says it supports that pixelformat, everything looks
fine, but it is not, and there is no way to find it out through the
links.
This patch was implemented so we could request any pixelformat from the
pipeline regardeless of the media bus format configured between pads.
Not all pixelformat can be mapped into a media bus code (e.g.
multiplanar formats), so with this patch we could request those
pixelformats from the tpg.
Solution: map pixelformats to media bus codes as before, and implement
conversions to other pixelformats in the capture to support multiplanar.
So first step to this solution is to revert this patch.

didn't return the chromakey correctly.
- G_FBUF didn't fill in many of the v4l2_framebuffer values.
Now also return the base address of the corresponding
framebuffer that this overlays.
- Missing ENUM/G/S_OUTPUT ioctls.
- ROTATE/VFLIP controls were added when the HW didn't support them.
With these changes 'v4l2-compliance' passes all non-streaming tests.
Tested on a Pandaboard and a Beagle XM board.
