Fix Makefile to include all copies of the SPD sources
On some systems there may be 2GB SKU that is the same as the
4GB SKU but just one channel of memory. In that case we need
to ensure that both copies of the same SPD source end up
populated by ensuring that repeated entries are included by
using $+ instead of $^.
Alternatively we could do the check inside romstage, but it
is already set to behave this way if the SPD gets populated
correctly.
I changed spd_index to 3 in falco romstage to force it to
pretend it was a 2GB config of the same memory, then booted
to ensure it was indeed limited to 2GB.
memcfg channel[0] config (00780008):
ECC inactive
enhanced interleave mode on
rank interleave on
DIMMA 2048 MB width x16 single rank, selected

memcfg channel[1] config (00600000):
ECC inactive
enhanced interleave mode on
rank interleave on
DIMMA 0 MB width x8 single rank, selected
