Add support for parallel flash on Dr. Kaiser PC-Waechter PCI devices
The vendor sold different designs under that name, the patch works with
the one that has an Actel FPGA as PCI-to-Flash bridge.
The Flash chip is a "Macronix MX29F001B" (128 KB, parallel) soldered
directly to the PCB.
Flash operations (PROBE, READ, ERASE, WRITE) work as expected.
Corresponding to flashrom svn r712.
