ARM: mx3/mx31moboard: properly allocate memory for mx3-camera
It's not allowed to create an alias of system RAM for DMA. So the memory
used must not be allocated using dma_alloc_coherent but has to be reserved
before using memblock routines.
There is no need to memzero the buffer because dma_alloc_coherent zeros
the memory for us.
