Karthikeyan Ramasubramanian 9e45e32420 util/spd_tools: Add support for Phoenix platform
Update spd_gen and part_id_gen utilities to accommodate Phoenix platform
so that SPD can be generated for the memory parts used in that platform.
SPD requirements for Phoenix and Mendocino platforms are identical.

BUG=b:273383819
TEST=Run spd_gen and ensure that both Mendocino and Phoenix platforms
share the platform manifest for LP5 memory parts.

Caveh Jalali c762e231da util/spd_tools: Update LP5X support for ADL/RPL/MTL
This updates the SPD utility and generated SPDs for LP5X to use memory
type code 0x15 (LPDDR5X) instead of 0x13 (LPDDR5). This is done based on
Intel Tech Advisory Doc ID #616599 dated May 2022, page 15.

SPDs were regenerated with:

Reka Norman b05edb1fea util/spd_tools: Implement a unified version of the part_id_gen tool
Currently there are two versions of gen_part_id.go, one for LP4x and one
DDR4. This change implements a unified version of this tool.

The new part_id_gen.go is almost identical to the existing
ddr4/gen_part_id.go. The new version was based on the ddr4 version and
not the lp4x version, since the ddr4 version contains extra logic to
support fixed IDs in the mem_parts_used files.

The only non-trivial change from ddr4/gen_part_id.go is to include the
full paths of SPD files in the generated Makefile.inc. E.g. instead of

  SPD_SOURCES += lp4x-spd-1.hex

the full path relative to the coreboot root directory is included:

TEST=For each variant of brya/volteer/dedede/guybrush/zork, run
part_id_gen and verify that the generated Makefile.inc and
dram_id.generated.txt are identical to those currently in the src tree,
except for the modified SPD file paths in Makefile.inc.
Example:
util/spd_tools/bin/part_id_gen \
  spd/lp4x/set-0 \
  src/mainboard/google/brya/variants/kano/memory \

Reka Norman 0e79274d33 util/spd_tools: Implement a unified version of the spd_gen tool
Currently there are two versions of spd_tools: one for LP4x and one for
DDR4. This change is the first step in unifying these into a single
tool.

This change implements a unified version of the spd_gen tool, by
combining the functionality currently in lp4x/gen_spd.go and
ddr4/gen_spd.go. The unified version takes the memory technology as an
argument, and generates SPD files for all platforms supporting that
technology.

BUG=b:191776301
TEST=Compare the SPDs generated by the old and new versions of the tool
for all supported platforms. For reference, the test script used is
here: https://review.coreboot.org/c/coreboot/+/57511
