Subject: [PATCH] sh: ecovec24: remove FSI/DA7210/Simple-Audio-Card support

Ecovec24 is using Simple-Audio-Card with "platform data" style
(which is mainly supporting "DT style" today), but "platform data"
style is not working correctly working during almost 10 years.

And DA7210 which is used in Ecovec24 was prototype version, and has
diff between production version. The driver doesn't care about it.

Ecovec24 sound doesn't work in these days, and there has been no
such report. Let's remove sound support.
