The MDMA0 controller clock needs to be enabled to allow the system to be resumed when entering into a suspend state.
The clock is disabled as a part of the runtime pm for the pl330 DMA driver so the system fails to resume. So to allow the system to grab the clock and make sure that it stays enabled during suspend, an alias has to be added so a clock lookup for a clock is registered.
