of: Move of_platform_register_reconfig_notifier() into DT core

There's no reason the generic platform bus code needs to call
of_platform_register_reconfig_notifier(). The notifier can be setup
before the platform bus is. Let's move it into of_core_init() which is
called just before platform_bus_init() instead to keep more of the DT
bits in the DT code.
