[coreboot] [PATCH] ht init and some errata for AMD fam 10 RB_C3

[xdrudis]

Hi.

This is the rest of patches to get until fidvid or staring 
ram stage, apparently at random. In fact once I've cleaned 
up the other patches a little I can't seem to make it stop at fidvid 
as it used to, but I guess with a dozen more tries it will...

It's including RB-C3 in AMD_FAM10_ALL
and adding some patches. It misses constants for new models 
that should also get some errata treatment.

It applies to 5703 with patch.warnerror, patch.serial1, and 
patch procnames, together with the new m4a77td-pro dir I haven't 
sent.

I know I should split it to smaller pieces, I just haven't had 
the time yet, and there's some overlap, so I must take care...
