ASoC: kirkwood-dma: remove IEC958_SUBFRAME formats
The Audio block does not support IEC958 subframes as formatted by
ALSA: they're very close, but not close enough. The formats differ
by:
3 2 2 2 1 1
1 8 4 0 6 2 8 4 0
PCUVDDDDDDDDDDDDDDDD....AAAATTTT - IEC958 subframe
PCUV0000........DDDDDDDDDDDDDDDD - Audio block format
Where P = parity, C = channel status, U = user data, V = validity,
D = sample data, A = aux, T = preamble. As can be seen, the
position of the sample is in a different position, and the audio
block does not have the aux or preamble bits.
