[coreboot] [PATCH-v2] Repair vsmsetup on GX2

[Nils]

Hi Stefan,
It sounds indeed better to move the GDT above 1MB.
But i think that it is not fair to say i moved it down, because it never was 
above 1MB on GX2 (non-car) boards, see options.lb .

It did`t give any build errors on kconfig because real_mode_switch_call_vsm was 
commented out and some other things were removed therefor vsm loading is 
broken on GX2 for at least 5 months.
I think the automated Kbuild system is a nice method to check patches but when 
a board gets broken to shut of build errors I think there is something wrong.
I think all the new improvements in coreboot are really nice but the downside 
is that (reading the list for quite some time) probably 90 percent of the 
boards do not work anymore and almost nobody tests them.
My priority would be to get as much boards as possible working again and then
improve them if possible.

As these are my first programming steps (mostly copy and paste) i won`t be able
to follow your suggestions.
I hope someone else knows how and has the time to do it.

Thank,Nils.

P.s. My patch for MSRTOOL from some time ago has had not much interest also.
