google/chell: 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 by comparing the generated ACPI code in the SSDT
to what was in mainboard.asl and ensuring the contents are
functionally equivalent.
