[coreboot] PATCH: lx loads payload again, with new vsa, proper PCI bus scan etc.

[ron minnich]

With this set of changes, the lx target loads VSA and configures the PCI bus,
with VSA operating correctly. This is tested with AMD's recently released
new-model VSA code. Note that v3 build is correctly compressing the uncompressed
vsa payload. I am really happy with v3 so far.

Sadly, the first jump to payload crashes and burns. Marc, can you
check this with fs2 for me? I still have not found mine ...

PS: PLEASE, if you are going to the coreboot summit April 3-5,
register at hpcsw.org. You can get good rates at the hotel through
april 6 even. I am staying there through sunday.

thanks
