ASoC: SOF: Intel: hda-mlink: special-case HDaudio regular links

Browse source

For backwards compatibility, HDaudio/iDISP links are powered-on when
exiting reset, and the existing driver forces them to be powered-off
when entering S0ix. In addition, the get/put helpers are invoked
directly by the ASoC codec drivers, which a historical layering
violation.

Extended links are powered-on by software only, during the probe and
DAI startup phases. This calls for a different handling of the
'regular' and 'extended' audio links.
