[PATCH 06/12] ARM: mxc: Setup consistent dma size at boot time

Hi Sascha, does the following revised patch gain receive your
Acked-by?...

From: Jon Medhurst <tixy at yxit.co.uk>

All in tree MX boards using video use memblock_* functions to get their coherent
dma space for the camera, so there is no need to increase CONSISTENT_DMA_SIZE
beyond the default and we can simply remove the defines which do this.
