ASoC: simple-card: remove platform data style

Simple-Card has created for "platform data" style first, and expanded
to "DT style". Current Simple-Card "platform data" style should not
work during almost 10 years, but no one reported it.

No one is using "platform data" style. Let's remove its support.
