In the patch, widgets, routes and dai-link requrird by SOF are included, and late_probe is introduced for SOF route connection.
Only when adsp phandle could be retrieved from DTS, the SOF related part of machine driver is executed.
Additionally, supported dai-links could be specified from DTS, so that we can disable AP side hardware controls when DSP SOF controls the same audio FE.
