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.

Chromium sources used:
firmware-banjo-5216.334.B 32ec493 [chromeos: vboot_loader: Set...]
firmware-candy-5216.310.B 519ff11 [baytrail: Preserve VbNv around...]
firmware-clapper-5216.199.B 80d55e3 [baytrail: add code for...]
firmware-glimmer-5216.198.B fae0770 [baytrail: add code for...]
firmware-gnawty-5216.239.B 952adb7 [Gnawty/Olay: Add 2nd source...]
firmware-heli-5216.392.B f1f3604 [helis: Lock ME / TXE section...]
firmware-kip-5216.227.B db3c5d9 [kip: update spd for for MT41K256M16*]
firmware-orco-5216.362.B 76f1651 [Orco: Adjust rx delay for norm.]
firmware-quawks-5216.204.B edb60c9 [Quawks: Update SPD data]
firmware-squawks-5216.152.B c6573dc [Squawks: Update SPD data]
firmware-sumo-5216.382.B c62b6f23 [Ninja, Sumo: Add SPD source...]
firmware-swanky-5216.238.B 233b2a7 [Swanky: update SPD table]
firmware-winky-5216.265.B ce91ffc [Add to support HT Micron...]

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
