Pass a drm pixel format fourcc to ipu_cpmem_set_yuv_interleaved(),
ipu_cpmem_set_yuv_planar_full(), and ipu_cpmem_set_yuv_planar(),
instead of a v4l2 pixel format. The remaining cpmem API that still
accepts a v4l2 format is now only ipu_cpmem_set_image(), since this
function is called by v4l2 drivers.
