Add Baytrail ChromeOS devices using variant scheme
Add new ChromeOS devices banjo, candy, clapper, glimmer, gnawty,
heli, kip, orco, quawks, squawks, sumo, swanky, and winky using
their common reference board (rambi) as a base.

The same basic cleanup/changes are made here as with the initial BYT
variant commit:
- remove unused ACPI trackpad/touchscreen devices
- correct I2C addresses in SMBIOS entries
- clean up comment formatting
- remove ACPI device for unused light sensor
- switch I2C ACPI devices from edge to level triggered interrupts,
for better compatibility/functionality (and to be consistent
with other recently-upstreamed ChromeOS devices)
- Micron 2GB SPD file for kip with updated values renamed to distinguish
from same file used by other boards
