sh: 7724se: remove FSI/AK4642/Simple-Audio-Card support
7724se 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.
7724se sound doesn't work in these days, and there has been no
such report. Let's remove sound support.
