This implements support for devices using AMD Geode companion chip
CS5536 that have the Boot ROM on NOR flash that is directly connected to
FLASH_CS3 (Boot Flash Chip Select). We need to write enable it in the
NORF_CTL MSR register for flashrom to be able to write to it, including
JEDEC probe commands.

This patch allows us to stop using AMD gx_utils.ko for BIOS flashing on
the DBE61.

Corresponding to flashrom svn r192 and coreboot v2 svn r3097.
