[media] gspca_t613: convert to the control framework
Changes by Hans de Goede: -rework how gain controls work to better match control framework -make awb + gain + red/blue-balance a single auto-cluster -only add the HFLIP control for TAS5130a sensor cams, as it breaks the video on other cams Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
