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.
