[flashrom] [PATCH] add support for Asus P4S800-MX

[David Borg]

Patch to add support for the Asus P4S800-MX motherboard and SIS 963
chipset. Invalidates previous patch: [PATCH] add support for SIS963

If anyone has the output of superiotool -deV for the following working
boards, please forward them, so I can merge the functions
w836xx_unlock_memw_enable_2e and w836xx_memw_enable_2e, and maybe fix
the function w836xx_memw_enable which I believe has a typo, such that
                sio_mask(port, 0x24, 0x28, 0x28);
becomes : sio_mask(port, 0x24, 0x28, 0x38);

Motherboards:
Albatron - PM266A Pro
ASUS - A7V8X-MX SE
EPoX - EP-8K5A2
Shuttle - AK31
Tyan - S2498 (Tomcat K7M)
