bus: mhi: ep: Add support for powering down the MHI endpoint stack
Add support for MHI endpoint power_down that includes stopping all
available channels, destroying the channels, resetting the event and
transfer rings and freeing the host cache.
The stack will be powered down whenever the physical bus link goes down.
