[RFC PATCH 0/3] ASoC: Intel: Add Lenovo Yoga Book RT5677 support

[Maurizio Casciano]

The Lenovo Yoga Book YB1-X91F/L uses a Cherry Trail SSP2 connection to
an RT5677 codec, with board-specific amplifier, headphone and headset
detector wiring.  Add the machine driver, the SST machine-table match,
and the SOF topology filename used by the corresponding external SOF
topology.

The companion platform/x86 series supplies the TS3A227E device and codec
GPIO lookup entries.  The sof-cht-rt5677.tplg topology is maintained in
the SOF project and must be merged and distributed separately.

With the matching topology installed, the Yoga Book reaches the SOF
card-registration and stream setup path.  End-to-end playback and
capture acceptance is not complete, so this is posted as an RFC.
