Albert ARIBAUD \(3ADEV\) db74cbfc09 pcm052: fix DDR initialization sequence
The sequence erroneously launched the DDR controller
initialization before the pad muxing was done, causing
DRAM size computation to hang.

Configuring the pads first then launching DDR controller
initialization prevents the DRAM hanging.
