This adds support for the SDM660 (formerly "SDM660 internal") sound
card and support for WCD codecs over internal MI2S.

Like on MSM8916 and MSM8953, some SDM660 and SDM670 devices connect to a
digital and analog codec. The connection to the digital codec is through
special "internal" MI2S ports. The digital and analog codecs are used on
the Xiaomi Redmi Note 7 for headset (playback + capture) and earpiece,
and also on the Google Pixel 3a for the headset.

This series does not include devicetree patches.
