[media] btcx-risc: move from media/i2c to media/common
The btcx-risc module is a helper module for bttv/conexant based TV cards. It isn't an i2c module at all, instead it should be in common since it is used by 4 pci drivers. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
