	[media] tvp5150: replace MEDIA_ENT_F_CONN_TEST by a control
MEDIA_ENT_F_CONN_TEST is not really a connector, it is actually a signal generator. Also, as other drivers use the V4L2_CID_TEST_PATTERN control for signal generators, let's change the driver accordingly. Tested with Terratec Grabster AV350.
