Leah Rowe 2edd583aee Add ThinkPad X270 coreboot port from Kat Inskip
Courtesy of Kat Inskip who ported this board.

Headphone output doesn't work at the moment, due to incorrect verb.
Intel VBT is also wrong. Both are taken from another board.

This will be amended later with the correct verb and VBT.
