This patch set adds per backend support of hardware drivers.  All hardware
drivers are assigned to a specific backend.  When looking up a driver
for a target in device tree, first lookup the specific backend and then
the default backend.  The same compatible property can be used to load
different hardware drivers depending on different backend.  As a result,
the compatible properties in device tree do not need to be hardware
specific.  The compatible properties in system device tree will allow
looking up either architecture specific driver (e.g. ibm,power9-thread)
or an architecture-neutral driver (e.g. ibm,power-thread).
