SoC and mainboard code accordingly.
TEST=Verified that UPDs are configured correctly with and without this
change.

Add a common routine meminit_ddr() that calls the appropriate meminit
routine based on whether the memory type requested is LPDDR4x or DDR4.

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

This change reorganizes memory initialization code for LPDDR4x on
TGL to allow sharing of code when adding support for other memory
types. In follow-up changes, support for DDR4 will be added.
1. It adds configuration for memory topology which is currently only
MEMORY_DOWN, however DDR4 requires more topologies to be
supported.
2. spd_info structure is organized to allow mixed topologies as well.
3. DQ/DQS maps are organized to reflect hardware configuration.
TEST=Verified that volteer still boots and memory initialization is
successful.
