Write enable flash chips attached to CS3 of CS5536 chipsets (AMD Geode)
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.
