From 9308ee506aa7a68c8af387e9c94956cf8cc4fbd5 Mon Sep 17 00:00:00 2001

Subject: ASoC: simple-card: simplify code

In the non-DT sequence, the platform data is copied as a whole to the
dynamic card info and the same pointer 'cinfo' is used to copy the
platform information to the card.

Use 'priv' as the pointer to the dynamic card info and copy only the
useful information from the platform data.
