If a memory part is a x16 part that has two dies and only a single
rank, then the x16 describes the part width (since this solution will
need to be a stacked solution) and as such, we must translate the
DeviceBusWidth to the "die bus width" instead.
Change DeviceBusWidth variable name to PackageBusWidth to be more
descriptive
BUG=b:166645306, b:160157545
TEST=run gen_spd and verify that spds for parts matching description
above changed appropriately.

Now that generic SPD files have the memory type prepended to the
filename, they can be stored in the same location. This CL moves
the generic SPDs to the new location.
Change the ddr4 gen_part_id.go and gen_spd.go tools to use
"ddr4_spd_manifest.generated" instead of "spd_manifest.generated".
Change the lpddr4x gen_part_id.go and gen_spd.go tools to use
"lp4x_spd_manifest.generated" instead of "spd_manifest.generated".
Move TGL DDR4 and LPDDR4x generic SPDs into a common location.
Move JSL DDR4 and LPDDR4x generic SPDs into a common location.
Change the volteer/spd/Makefile.inc to use the new path for the spds.
Change the dedede/spd/Makefile.inc to use the new path for the spds.

Serial Presence Detect (SPD) data for memory modules is used by Memory
Reference Code (MRC) for training the memory. This SPD data is
typically obtained from part vendors but has to be massaged to format
it correctly as per JEDEC and MRC expectations. There have been
numerous times in the past where the SPD data used is not always
correct.
In order to reduce the manual effort of creating SPDs and generating
DRAM IDs, this change adds tools for generating SPD files for DDR4
memory used in memory down configurations on Intel Tiger Lake (TGL)
based platforms. These tools generate SPDs following JESD79-4C and
Jedec "4.1.2.L-5 R29 v103" specification.
Two tools are provided:
* gen_spd.go: Generates de-duplicated SPD files using a global memory
part list provided by the mainboard in JSON format. Additionally,
generates a SPD manifest file (in CSV format) with information about
what memory part from the global list uses which of the generated
SPD files.
* gen_part_id.go: Allocates DRAM strap IDs for different DDR4
memory parts used by the board. Takes as input list of memory parts
used by the board (with one memory part on each line) and the SPD
manifest file generated by gen_spd.go. Generates Makefile.inc for
integrating the generated SPD files in the coreboot build.

As per JEDEC spec, manufacturer part name should be set to
blank (0x20). This change updates gen_spd.go to set bytes 329-348 as
0x20 and regenerates SPDs for TGL and JSL.

This change uses gen_spd.go and global_lp4x_mem_parts.json.txt to
generate SPD files for currently known LP4x memory parts that can be
used with TGL-based mainboards.
Following files are added:
1. spd-*.hex: SPD files auto-generated by gen_spd.go
2. spd_manifest.generated.txt: Manifest file auto-generated by
gen_spd.go
Mainboards can use the SPD files from SoC directly when creating SPD
binary to add to CBFS.
