mb/google/volteer: add generic DDR4 SPDs for Eldrid
Add Makefile.inc to include six generic DDR4 SPDs for the following parts for Eldrid:
DRAM Part Name DRAM ID to assign H5AN8G6NDJR-XNC 0 (0000) MT40A512M16TB-062E:J 1 (0001) H5ANAG6NCMR-XNC 2 (0010) K4A8G165WC-BCWE 0 (0000) K4AAG165WA-BCWE 3 (0011) MT40A1G16KD-062E:E 3 (0011)
Add mem_list_variant.txt as a manifest of eldrid's DRAM parts for use by gen_spd, the generic DD4 SPD generation tool.
Add dram_id_generated.txt to specify DRAM ID strap settings.
NOTE that Eldrid specified DRAM IDs for the first three parts to be 0 though 2 (i.e. no combined DRAM IDs for parts that use the same SPD).
BUG=b:161772961 TEST="FW_NAME=eldrid emerge-volteer coreboot" and verify it builds without error.
