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
