coreboot/fam15h: only use this, for amd boards
it is identical to fam15h_rdimm, with _udimm now removed;
the latter had a patch that added certain behaviour only
intended for rdimm, but the patch in question breaks various
configurations.
raminit has always been unreliable on these boards. i'd rather
simplify it all, in lbmk. i'll probably update this to the dasharo
tree later on, specificalyl for kgpe-d16
