Subject: [PATCH/RFC 6/6] Revert "driver core: platform_bus: allow runtime override of dev_pm_ops"

This reverts commit c64a0926710153b9d44c979d2942f4a8648fd74e.

The platform_bus_set_pm_ops() is deprecated in favor of the new device
power domain infrastructre implemented in commit
7538e3db6e015e890825fbd9f8659952896ddd5b (PM: add support for device
power domains)
