mb/google/brya: Add SPD configs for nivviks and nereid

Add a mem_parts_used.txt for each of nivviks and nereid, containing the
memory parts used in their pre-proto builds. Generate Makefile.inc and
dram_id.generated.txt using part_id_gen.

nivviks:
Micron MT62F1G32D4DR-031 WT:B

nereid:
Samsung K3LKBKB0BM-MGCP

BUG=b:197479026

contains an spd.bin.
