[0/7] media: kill off broken soc_camera

The soc_camera driver (and soc_camera.h header) is obsolete and depends
on BROKEN. It's time to remove this driver and the last references to it.

The first two patches remove a SoC Camera reference in two media drivers.
These references are obsolete (these drivers no longer use soc_camera),
so update the MODULE_DESCRIPTION.

The next three patches remove soc_camera depencies in three board files.
This has been compile tested. Note that the camera support for those
boards has been dead for a long time, so this really removes it. These
three patches are independent of the other patches in this series.

Then the soc_camera driver itself is removed (including soc_camera
dependent sensor drivers). This patch is also independent of the
other patches.

The final patch removes the soc_camera.h header, and that requires
that patches 3-6 are all merged.

Regards,

	Hans

This statement is not accurate, pxa_camera should be working in platform_data
based boards, it's just that the solution to make it work was not found yet if I
remember correctly, since the evolutions to the clocking in v4l2 hit it.

So be it.
