Maybe better named AUDIO_MMIO, as VERBS are a subset of that imo.

Let's also rename this to AUDIO_PLAYBACK for clarity.

Let's keep the order for other platforms and move DG1_PW_2 after
the DG1_PW_3 definition.

What about DC3co? I read about this change on HSD 1407435623:
"DC3 clock off mode is not possible with this mode since cdclk cannot be turned off."

Will DMC take care of this?

Could you please open a ticket to clarify the
"Audio codec idle and disabled."
DC3co requirement text wrt. this change on the BSpec/49196 page?

What about the D13 platform? Looks like it has the same split between
the MMIO and playback audio functionality.

Let's follow the order of platform definitions and move this after the
rkl power well list.
