Please find appended.  This patch gets rid of the %gs magic altogether,
fixes a few alignment wrinkles and sets up and registers the MMCONF area
for AMD Fam10h CPUs (where selected by mainboard configuration).  It
removes a bit of code that proved troublesome in MMCONF setups from
mcp55_early_setup_car.c, as per earlier discussion.

(The way the patch hooks add_northbridge_resources via
s2912_fam10/mainboard.c replicates a well-used pattern that perhaps
ought to be simplified.  HAVE_NORTHBRIDGE_RESOURCES would remove
otherwise empty add_mainboard_resources from a lot of mainboard.c
