During my recent work on the bytcht-es8316 UCM profile I realized that the
bytcr-rt5651 devices with a single speaker use a differential setup just
like the es8316 does. The tell-tale here is the speaker going quiet when
playing the exact same sound on both channels when things are configured
for stereo speakers.
I've run some tests and the rt5651 does have a special mono balanced out
mode for its line-out but using this results in the same sound (and the
same loudness / volume of the sound) as our current solution, so adding
support for this to the kernel buys us nothing.
This commit makes no changes, it just documents my findings in a big
comment for future reference.

Add a new ucm/codecs/rt5651/DigitalMic.conf snippet for digital mic support
and include this in the default non board-specific bytcr-rt5651.conf.

The first design with the headset-mic on IN2 rather then the
default / reference-design IN3 has shown up.
Add a new ucm/codecs/rt5651/IN2-HeadsetMic.conf snippet to deal with this
and include this in the default non board-specific bytcr-rt5651.conf.

Explicitly enable the right 'Stereo? ADC MIXL ADC?' when selecting an input,
rather then just enabling them all in ucm/codecs/rt5651/EnableSeq.conf .
This is a preparation patch for adding digital mic support.

We have placed UCM profile snippets to be included by the main config
files also in the same directory, src/conf/ucm, it confuses alsaucm
program that scans over all subdirectories. It thinks such a file is
also the main config file, and spews errors like:
% alsaucm
ALSA lib utils.c:67:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm/bytcr/bytcr.conf
ALSA lib parser.c:1427:(load_master_config) error: could not parse configuration for card bytcr
alsaucm: unable to obtain card list: No such file or directory
Actually we already defined the subdirectory for such components, and
they are skipped at parsing the main configs. So we just need to move
the files there -- this is what's done here.
One more thing done here is to add a new component subdirectory,
platforms, for definitions bytcr/* that don't match with neither the
existing ones (codecs nor dsps).
