Add/Combine Haswell Chromebooks using variant board scheme

Combine existing boards google/falco and google/peppy with new
ChromeOS devices leon and wolf, using their common reference board
(slippy) as a base.

Chromium sources used:
firmware-falco_peppy-4389.81.B d7703cac [falco: Add support for Samsung...]
firmware-leon-4389.61.B ea1bf55 [haswell: Enable 2x Refresh Mode]
firmware-wolf-4389.24.B 7c5a9c2 [Wolf: haswell: Add small delay before...]

Additionally, some minor cleanup/changes were made:
- I2C devices set to use ACPI (vs PCI) mode
- I2C device ACPI entries adjusted as per above
- I2C devices set to use level (vs edge) interrupt triggering
- XHCI finalization enabled in devicetree
- HDA verb entries use simplified macro entry format

Existing google/falco and google/peppy boards will be removed in a
subsequent commit.

Variant setup modeled after google/beltino
