dp8393x: remove onboard PROM containing MAC address and checksum
According to the datasheet the dp8393x chipset does not contain any NVRAM capable of storing a MAC address or checksum. Now that both the MIPS jazz and m68k q800 boards generate the PROM region and checksum themselves, remove the generated PROM from the dp8393x device itself.
