[coreboot] Geode LX/CS5536 VSA

[Marc Jones]

Geode LX/CS5536 VSA has been updated. The source and binary are 
attached. With this release we have changed how the binary is packaged. 
Previously it was posted alread compressed with nrv2b and padded to 
size. Going forward it is GZipd and will need to be compressed and 
padded by hand or by buildrom.

Instructions available here:
http://www.coreboot.org/AMD_Geode_Porting_Guide

The following changes were made:
Remove int15 callbacks removed. CPU and memory are calculated by VSA.
VSA no longer takes all the MFGPTs. Two are now available for OS use.

The VSA binary is always available here:

buildrom and v2 patches to follow.
