[media] feature-removal: update V4L1 removal status
While the V4L1 compatibility module has been removed, we still have
two V4L1 drivers that prevent full V4L1 removal.
Those drivers have been moved to staging and will be removed in 2.6.39,
together with the last V4L1 support.

Those drivers are for obsolete hardware that the old maintainer didn't care (or not have the hardware anymore), and that no other developer could find any hardware to buy. They probably have no practical usage today, and people with such old hardware could probably keep using an older version - of the kernel.
