PM: Revert "driver core: platform_bus: allow runtime override of dev_pm_ops" 

The platform_bus_set_pm_ops() operation is deprecated in favor of the
new device power domain infrastructre implemented in commit
7538e3db6e (PM: add support for device
power domains)

* platform code will first do a platform_bus_get_pm_ops(), then
* kmemdup it, then customize selected methods and pass a pointer to

* Since platform-specific code is customizing methods for *all*
* devices (not just platform-specific devices) it is expected that
* any custom overrides of these functions will keep existing behavior
* and simply extend it. For example, any customization of the
* runtime PM methods should continue to call the pm_generic_*
* functions as the default ones do in addition to the
* platform-specific behavior.
