bus: mhi: ep: Add support for sending events to the host
Add support for sending the events to the host over MHI bus from the
endpoint. Following events are supported:
1. Transfer completion event
2. Command completion event
3. State change event
4. Execution Environment (EE) change event
An event is sent whenever an operation has been completed in the MHI EP
device. Event is sent using the MHI event ring and additionally the host
is notified using an IRQ if required.
