Currently, one of the arguments to part_id_gen is the directory
containing the SPD files, e.g. spd/lp4x/set-0. This requires the user of
the tool to understand the spd/ directory structure, and manually look

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:
