Add Haswell Chromeboxes/Chromebase using variant board scheme

Combine existing board google/panther with new ChromeOS devices
mccloud, monroe, tricky, and zako, using their common reference board
(beltino) as a base.

Chromium sources used:
firmware-mccloud-5827.B 65bfee7 [haswell: No need pre-graphics delay...]
firmware-monroe-4921.B 1ac749d [Monroe: Disable KB/MS in ITE8772.]
firmware-tricky-5829.B 2db5322 [haswell: No need pre-graphics delay...]
firmware-zako-5219.B eacedef [haswell: No need pre-graphics delay...]

Existing google/panther board will be removed in a subsequent commit.

Variant setup modeled after google/reef
