google/chell: Convert to a variant of glados

Convert chell to a variant of glados Skylake reference board: - add chell-specific DPTF, EC config, USB port defs, GPIO config, NHLT config, PEI data, VBT, SPD data, and devicetree - add romstage handler to turn on keyboard backlight for boards so equipped - remove existing chell board/directory Test: build/boot google/chell, verify functionality unchanged from pre-variant configuration Change-Id: I7dfbafe3afcab7cee7bcb2bf91c6733c07b409c4 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/27412 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin Roth <martinroth@google.com>
