New commit message:

    drm/vc4: Don't try to initialize FBDEV if we're only bound to V3D.
    
    There's no sense in having an fbdev if there's no display, since
    connectors don't get hotplugged to this hardware.  On Cygnus we were
    getting a dmesg error from passing in num_connectors (0), when that
    argument is supposed to be the maximum number of cloned connectors per
    CRTC (1).

Still no drm-misc acks on the other two patches, so I don't think I can
merge them.
