purism/librem13v2: Add initial directory for librem13 v2

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.
