V4L/DVB (4701): Saa713x audio fixes
This change fixes the following issues: - resolve the SECAM D/K vs SECAM-L sound conflict It is now possible to select the SECAM version either by the VIDEOIOC_S_STD IO control or by the new secam= insmod option. The driver now adapts its audio standard search list to the selected standard. - don't trigger a sound standard search when a LINE input is selected.
