chromeos mainboards: remove chromeos.asl

Use the ACPI generator for creating the Chrome OS gpio
    package. Each mainboard has its own list of Chrome OS
    gpios that are fed into a helper to generate the ACPI
    external OIPG package.  Additionally, the common
    chromeos.asl is now conditionally included based on
    CONFIG_CHROMEOS.
