Add a quick and dirty FBIOGVIDEO implementation. This is hardware independent, 

by saving the last written FIOSVIDEO/GRFIOCBLANK value into a shadow variable
in the grf_softc and returning this value on FBIOGVIDEO.
The presence of this ioctl is needed by screenblank(8) nowadays.
Original problem reported by Lars Hecking on the port-amiga mailing list.
