[coreboot] [RFC]Dedefine DIMMx in romstage.c/spd_addr.h

[Patrick Georgi]

Hi,

two of the remaining defines that need to be eliminated from romstage.c
are DIMM0 and DIMM1, as these are used in some northbridges. That got me
thinking about moving all of DIMM0..DIMM7 to Kconfig, and how that could
look like.

The thing is, that we currently have lots of duplicate data
(DIMM0..DIMMx) in _many_ board directories that looks essentially the
same, there are maybe 5 or 6 different sets of values.
Are these northbridge specific (with the option that some boards
override them), or who is responsible for these values?
