google/glados: 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 verified on a glados board by verifying the SSDT contents
against what used to be in the DSDT.
