2021-09-23spd: Add SPD for 4JQA-0622AD to spd/Reka Norman
Since generating the SPDs under spd/, a new part was added in https://review.coreboot.org/57550. Regenerate the SPDs to include this new part.

2021-09-23util/spd_tools: Remove PLK platformReka Norman
Currently spd_tools treats PCO and PLK as separate platforms. This is unnecessary since they have the same SPD requirements. Remove PLK, and use PCO as the platform for all zork variants.

2021-09-23lib/Makefile.inc: Generate placeholder spd.bin in lib/Makefile.incReka Norman
When a new variant is created, it needs to have a path to its SPD binary defined. Currently, this is done by setting SPD_SOURCES to a placeholder SPD file, which just contains zero bytes. To remove the need for a placeholder file, automatically generate a single-byte spd.bin in lib/Makefile.inc when SPD_SOURCES is set to the marker value 'placeholder'. BUG=b:191776301 TEST=Change cappy/memory/Makefile to `SPD_SOURCES = placeholder`. Build and check that spd.bin contains a single zero byte.

2021-09-20spd: Add a placeholder SPD file to spd/Reka Norman
When a new variant is created, its SPD_SOURCES contains a placeholder file, to avoid a build failure due to SPD_SOURCES being empty. Currently these placeholder files live with the rest of the SPD files in soc and mainboard directories, e.g. src/soc/intel/alderlake/spd/placeholder.spd.hex Add a similar placeholder SPD file to the new spd/ directory.

2021-09-20spd: Generate SPDs under spd/ using unified spd_gen toolReka Norman
Use the new unified version of the spd_gen tool to generate all LP4x and DDR4 SPDs, storing them in a new spd/ directory. Storing them in a common location allows platforms with the same SPD requirements to share SPD files, reducing duplication compared to storing SPDs in soc/ and mainboard/ directories. For each memory technology there are multiple sets of SPDs. Each set corresponds to a set of platforms with different SPD requirements, e.g. due to different memory training code expectations. A manifest file (platforms_manifest.generated.txt) lists the platform -> set mappings.
