mb/google/auron: Add SATA PCI device to overridetree

`chip` entries are only hooked up via device nodes to the tree. A `chip`
without a `device` below it does nothing. To allow variants to override
SATA tuning parameters, ensure a device exists under the PCH chip scope.

Without this change, some variants would not properly override the SATA
tuning parameters after extracting the PCH parts into a different chip.

TEST=Sanity-check static.c and verify overridetrees override properly.
