media: Revert "media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci"
This reverts commit e33fdb5a02490059e2f48ced2c038c8a46c6476d. The saa7146-based devices are still in use, esp. for DVB. So move these drivers back to mainline. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
