dt: add of_platform_populate() for creating device from the device tree
of_platform_populate() is similar to of_platform_bus_probe() except that it strictly enforces that all device nodes must have a compatible property, and it can be used to register devices (not buses) which are children of the root node. This patch also modifies MPC5200 support to use the new function. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
