[media] saa7134: switch tuner FMD1216ME_MK3 to analog

The tuner FMD1216ME_MK3 suffers the same problem as FMD1216MEX_MK3,
as described in saa7134-cards.c (disabled IF, enabled DVB-T). The
card does work under MS Windows, after soft reboot into Linux it
continues to work, only then tda9887 is loaded as well.

The CTX946 TV card doesn't detect a signal after cold boot, seems
