dmaengine: PL08x: remove runtime PM support
The runtime PM support conflicts with the generic AMBA bus PM, and also causes a potential deadlock with the PL011 driver as it results in interrupts being enabled beneath a spinlock. I don't presently see any solution to this other than by removing the runtime PM support entirely from the DMA engine driver. Alternative suggestions welcome.
