media: usbtv: Add SECAM support
Add support for the SECAM norm, using the "AVSECAM" decoder configuration
sequence found in Windows driver's .INF file.
For reference, the "AVSECAM" sequence in the .INF file is:
0x04,0x73,0xDC,0x72,0xA2,0x90,0x35,0x01,0x30,0x04,0x08,0x2D,0x28,0x08,
0x02,0x69,0x16,0x35,0x21,0x16,0x36
