ASoC: Add Magician machine support
HTC Magician has a Philips UDA1380 codec connected via SSP1 (playback) and I2S (capture). There is a flip-flop between the SSP frame clock output and the codec's word select input pin. To make the codec see proper I2S input, the SSP has to send two frames per sample.
