V4L/DVB (4739): SECAM support for saa7113 into saa7115

Without the attached trivial patch, the saa7113 is set up for PAL when SECAM 
is selected and hence will see only show black and white for SECAM signals.
Tested the patch against the saa7115 module in linux-2.6.17 with a 
Pinnacle 50e USB tuner (em28xx).
