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 Change-Id: Iae7855af9a224fd4cb948b854494e39b545ad449 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/18129 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>
