On memory limited devices, CMA fails easily when asked to allocate big
chunks of memory like framebuffer memory needed for video playback.
Add boot parameter "omapfb_memsize" which allocates memory to be used
as dma coherent memory, so dma_alloc_attrs won't hit CMA allocator when
trying to allocate memory for the framebuffers
