Currently the VPU allocates the contiguous buffer for the framebuffer. Try an alternate path first where we use dma_alloc_coherent and pass the buffer to the VPU. Should the VPU firmware not support that path, then free the buffer and revert to the old behaviour of using the VPU allocation. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
