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.
