Xc2028.3028 has two type of firmwares: audio-standard specific ones and baseband MTS firmwares. MTS firmwares provide stereo decoding for 6 MHz BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares. It seems that the option to use MTS or a standard-specific audio decoding depends on the way xc2028/3028 is connected. Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS firmware, this patch converts it to a bitfield that can be shared with other proprieties of xc2028/3028.
