Sascha Hauer 772a9e631c [PATCH] ARM: 2687/1: i.MX framebuffer: make dmacr register platform configurable
Patch from Sascha Hauer

The dmacr needs different settings on some boards. This patch makes the
register configurable by the platform part.
Also we have imxfb_disable_controller(), so lets use it.
