media: Revert "media: av7110: move to staging/media/deprecated/saa7146"
This reverts commit 3e9ad662e34eb2d42ddef5a2883abd34461dfd9a. The av7110 is still in use, so it can't be deprecated. Move it back to staging/media for now. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
