Delay matches of platform devices with OF nodes until late_initcall,

This is needed to prevent deferred probes because of some drivers not
having registered yet.

The reason why only platform devices are delayed is that some other
devices are expected to be probed earlier than late_initcall, for
example, the system PNP driver needs to probe its devices in
fs_initcall.

Additionally, only platform devices with OF nodes are delayed because
some machines may depend on oter platform devices being registered at
specific times.

How do we know that these probes occur before the unused clocks and
regulators are turned off? Just getting lucky (as is deferred probe)?
Can we do this one level earlier so we have a level left to do things
after probe.
