[PATCH v2 4/5] ARM: mxs: do not add dma device by default

[Dong Aisheng <b29396-KZfg59tc24xl57MIdRCFDg@public.gmane.org>]

From: Dong Aisheng <dong.aisheng-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

This will cause conflict when dt is enabled.
So let each platform add dma devices respectively.

ChangeLog v2->v3:
 * introduce mx23/mx28_soc_init()
ChangeLog v1->v2:
 * Add the missed mx28_add_dma() for mx28evk.c.
