[coreboot-gerrit] Change in coreboot[master]: mb/google/volteer: add support for ddr4 memory

[Nick Vaccaro (Code Review)]

Hello build bot (Jenkins), Furquan Shaikh, Caveh Jalali, Ravishankar Sarawadi, Duncan Laurie, Derek Huang,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/44250

to look at the new patch set (#2).

Change subject: mb/google/volteer: add support for ddr4 memory
......................................................................

mb/google/volteer: add support for ddr4 memory

Add new ddr_memory_cfg structure to support both DDR4 and LPDDR4x
memory types.

Change existing variant code to use the new meminit_ddr() call
instead of calling meminit_lpddr4x() directly.

BUG=b:161772961
TEST='emerge-volteer coreboot chromeos-bootimage' and verify that
volteer still boots.  NOTE that this only tests the lpddr4 side
of the implementation as I do not have a DDR4 board to test this on.
