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.
