cht-bsw-rt5672: Add Lenovo Miix 2 10 specific configuration

By default the cht-bsw-rt5672 config lets the user figure out if a device
has a Mono spaker or Stereo speakers and which DMIC input is used.

Since this is not very user-friendly we do regex matches on the DMI derived
longname to automaticaly select the right options (and to only advertise
those options).

This commit adds support for automatically selecting the right options
on the Lenovo Miix 2 10 tablet. Since this is the first device for which
we do longname matching using a DMIC on DMIC1, this also fixes a fixme :)
