gfxmatrox: Introduce new programmer driver for Matrox Millenium cards

Supports a 64KiB parallel flash. ROM BAR configuration is tricky: The
register is only accessible when a special `biosen` bit is set. An OS
might not know this and is then unable to assign an address. We'll of-
fer to re-purpose the MMIO BAR address, but one has to be sure that no
graphics driver is running.
