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.

ba478f2de5 mini.hv.dcp: Decode common messages
This accounts for most of the DCP traffic once macOS is booted. I used
a sophisticated side-channel hypervisor timing attack to determine the
message functions [ adding time.sleep(1) ]
