DPU power handler maintained PRE/POST versions of power ENABLE/DISABLE events to accommodate tasks which need be handled before/after data bus voting. But since the bus voting API's are deprecated and removed from the driver, squash the events and their clients respective event handlers to handle only ENABLE/DISABLE events.
changes in v5: - introduced in the series changes in v6: - define macro values using BIT(x) (Sean)
