Combine Baytrail ChromeOS devices using variant scheme

Combine existing boards google/enguarde and google/ninja using
their common reference board google/rambi as a baseboard.

Variants contain board specific data:
 - DPTF ACPI components
 - I2C ACPI devices
 - RAM config / SPD data
 - devicetree config
 - GPIOs
 - board-specific HW components (e.g., LAN)

Additionally, some minor cleanup/changes were made:
 - 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)

The existing enguarde and ninja boards are removed.

Variant setup modeled after google/auron
