[POWERPC] Add a unified uevent handler for bus based on of_device
This common uevent handler allow the several bus types based on
of_device to generate the uevent properly and avoiding
code duplication.
This handlers take a struct device as argument and can therefore
be used as the uevent call directly if no special treatment is
needed for the bus.
