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.
