gst: Don't ask for DMA buffers

Browse source 
Gstreamer simply mmap()s the DMA buffers. This can be very very slow on
some hardware, so don't ask for it. For gstreamer to support DMA
buffers, it will need to support a proper way of transferring the
buffers from the GPU to the CPU, e.g. using EGL/OpenGL.
