ivtv: avoid green flashing when loading ivtv
From: Martin Dauskardt <martin.dauskardt@gmx.de>
When loading ivtv the TV-out of the PVR-350 will flash green since the
saa712x is activated before the MPEG decoder has been initialized.
Deactivate the saa712x until the MPEG decoder has been initialized.
Priority: normal
