Second version adding support for mono audio links in OMAP McBSP DAI. At this
time, the channels_min is defined to 1 in omap-mcbsp.c and no hacks in
machine drivers wanting to use mono link are required.

If channel restrictions are required, then machine driver can use
snd_pcm_hw_constraint_minmax. Now only N810 machine driver is affected since
all other OMAP machine drivers are using TWL4030 or TLV320AIC23 codecs which
all claim to support only 2 channels so the link remains always stereo even
playing mono audio.
