google/lars: Move devices from mainboard.asl to devicetree
Declare the mainboard attached devices in the devicetree and enable the provided device drivers by default to generate the ACPI objects for these devices. Then remove the static ACPI objects from the DSDT in mainboard.asl. This was tested on a Chell mainboard since I lack a lars device.
