Add/Combine Broadwell Chromebooks using variant board scheme
Combine existing boards google/auron_paine and google/samus with new
ChromeOS devices auron_yuna, gandof and lulu, using their common
reference board (auron) as a base.
Chromium sources used:
firmware-yuna-6301.59.B 6ed8b9d [CHERRY-PICK: broadwell: Update to...]
firmware-gandof-6301.155.B 666f34f [gandof: modify power limiting for...]
firmware-lulu-6301.136.B 8811714 [lulu: update RAMID table]
Additionally, some minor cleanup/changes were made:
- I2C devices set to use level (vs edge) interrupt triggering
- HDA verb entries use simplified macro entry format
- correct FADT table header version
- remove unused ACPI device entries / .asl file(s)
- clean up ACPI code (e.g., trackpad on Lulu)
- adjust _CID for trackpad on Lulu in order to not load non-functional
Windows driver (does not affect Linux)
- remove unused header includes (multiple/various)
- correct I2C addresses used for SMBIOS device entries
- correct misc typos etc
The existing auron_paine samus boards are removed.
Variant setup modeled after google/slippy
