ASoC: Intel: add sof-rt5682 machine driver

The machine driver is a generic machine driver for SOF with rt5682
codec. it currently supports BYT/CHT/ICL/CML. Depending on the SOC
hdmi/speaker and DMIC support are added dynamically.

Only add information related to SOF since the machine driver was
only tested with SOF.
