glados: Implement Chrome OS specific handlers

Implement the required Chrome OS specific handlers to read the
    recovery mode, clear the recovery mode, read the lid switch state,
    and read the write protect state using the appropriate methods.

Also update the Chrome OS ACPI device to use the GPIO definitions
    that are exposed now by the SOC.

BUG=chrome-os-partner:43515
    BRANCH=none
    TEST=build and boot on glados and successfully enter recovery mode
