Alyssa Rosenzweig eb466796d8 fw.dcp: Add some stubs needed for modesetting 
This isn't enough to set the video mode yet but it gets us further. I
think allocate_memory/map_buf/powerOnDART need real implementations,
otherwise setting a video mode crashes the DCP in an APIODMA interrupt
handler, whatever that is.
