Update memory parameters based on memory type supported by
Elkhart Lake CRB:
1. Update spd data for EHL LPDDR4X memory
- DQ byte map
- DQS CPU-DRAM map
- Rcomp resistor
- Rcomp target
2. Add configurations for vref_ca & interleaved memory
3. Add EHL CRB on board LPDDR4X SPD data bin file
4. Update mainboard related FSPM UPDs as part of memory
initialization

Since there is no EC support on EHL CRB, this patch removes board
ID detection via EC (board_id.c & board_id.h) and its related
files. Temporarily removes variant_memcfg_config function in
romstage_fsp_param.c, will be added back when updating memory
configs later.

This is a initial mainboard code cloned entirely from jasperlake_rvp
aimed to serve as base for further mainboard check-ins.
This patch is based on TGL_upstream series patches:
https://review.coreboot.org/c/coreboot/+/37868
List of changes on top off initial jasperlake_rvp clone:
1. Replace "Jasperlake" with "Elkhartlake"
2. Replace "jsl" with "ehl"
3. Replace "jslrvp" with "ehlcrb"
4. Remove unwanted SPD file, add empty SPD as placeholder
6. Empty romstage_fsp_params.c, to fill it later with SOC specific
config
7. Empty GPIO configurations, to be filled as per board
8. Empty memory.c configurations, to be filled as per board
9. Add board support namely BOARD_INTEL_ELKHARTLAKE_CRB
10. Replace jslrvp variant with ehlcrb variant
Changes to follow on top of this:
1. Add correct memory parameters, add SPDs
2. Clean up devicetree as per tigerlake SOC
3. Add GPIO support
4. Update ehl fmd file to replace 32MB chromeos.fmd
