of_platform_populate() takes a subset of the device tree and turns it
into a set of platform_devices. At the same time it sets the
OF_POPULATED_BUS flag in each bus nodes so that of_platform_depopulate()
can undo the operation at a later time. However, it doesn't set the flag
on the root of the population tree which means that dynamic modifications
of the device tree at runtime will not create/destroy devices correctly.
Fix of_platform_populate() to set the OF_POPULATED_BUS flag on the node
it is called with.
