[media] go7007: i2c initialization changes for tw2804
Do i2c initialization via struct item as tw2804 has a 0x00 i2c address, so we need to use the I2C_CLIENT_TEN flag for validity. Signed-off-by: Volokh Konstantin <volokh84@gmail.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
