Convert the Purism Librem13v2 board to a variant setup,
in preparation of adding the librem15v3 as a new variant.
The 13v2 and 15v3 are nearly identical, so this minimizes new
code to add support for the latter.

Migrate the Librem13v2 from using FSP 1.1 to
the public/GitHub FSP 2.0 Skylake/Kabylake release:
- select FSP 2.0 in Kconfig
- adjust romstage/ramstage functions as required
- refactor pei_data functions
- remove VR_RING domain from devicetree (unsupported in FSP 2.0)
- add SataSpeedLimit parameter to work around power-related issue
when operating at SATA 6.0Gbps speed
TEST: build/boot Librem13v2, observe successful boot, lack of
SATA-related errors in dmesg.

The RComp values have been updated to match what is shown in the schematics.
Extracting the Memory configuration blob from the original BIOS (A blob
which contains the correct binary sequence matching the RComp values appears
in object with GUID 2D27C618-7DCD-41F5-BB10-21166BE7E143), I could find
and confirm the DQ and DQS mapping.
Small code cleaning in romstage.c with no effect.

Add the initial directory for the port of the Librem 13 v2.
The base implementation was copied from the google/chell directory
and the chell references were replaced. spd directory was removed
since the RAM is not soldered on the MB. The Kconfig, board_info.txt
and devicetree.cb files were modified to match the Librem 13 v2
hardware information. The romstage.c, mainboard.c, Makefile.in and
dsdt.asl were modified to remove chromeos specific code. The boardid.c,
chromeos.c, chromeos.fmd, cmos.layout, ec.c, ec.h and smihandler.c
files were removed from the tree, and the acpi directory was replaced
with the acpi directory from the purism/librem13 board.
These changes allow us to remove the references to chromeos specific
code and allow coreboot to compile when the librem13v2 board is selected.
