Log Message:
Add a platform device tree passthrough for device properties.  First,
the device's properties dictionary is consulted, and if it doesn't have
what we're looking for, we go ask the platform device tree.  The upshot
is that we can g/c (or not have to add) code that duplicates values from
the device tree into the properties dictionary (either in something like
device_register() or in a driver attachment front-end -- there are multiple
example of both in the system, currently), and everyone gets to use a
consistent interface (which will, over time, allow more code to de-duplicated).

Implement back-ends for ACPI, Sun OpenBoot, and OpenFirmware (including FDT).
