When booting with DT, there's a crash when omapfb is probed. This is
caused by the fact that omapdss+DT is not yet supported, and thus
omapdss is not probed at all. On the other hand, omapfb is always
probed. When omapfb tries to use omapdss, there's a NULL pointer
dereference crash. The same error should most likely happen with omapdrm
and omap_vout also.
To fix this, add an "initialized" state to omapdss. When omapdss has
been probed, it's marked as initialized. omapfb, omapdrm and omap_vout
check this state when they are probed to see that omapdss is actually
there.

Originally struct v4l2_capability driver and card name was filled
with name of the platform device. After switching to the device tree
the device names have changed and now are 4 different driver names
reported, depending on the video device opened. So instead of e.g.
"exynos4-fimc" there is now one of: 11800000.fimc, 11810000.fimc,
11820000.fimc, 11830000.fimc.
Fix this by using dev->driver_name, rather than platform device name.
A common vidioc_querycap function is created for both M2M and capture
video node.
This fixes any breakage at user space should any application/library
rely on the driver's name.
