The pl330 can be behind an IOMMU which is the case for Arm Juno board.
Add the 'iommus' property allowing for 1 IOMMU entry per channel for
writes and 1 IOMMU entry for reads.

The pl330 DMA controller on Exynos SoC (e.g. dma-controller@3880000 in
Exynos5420) belongs to power domain, so allow such property.

Convert the Arm PL330 DMA controller binding to DT schema.
The '#dma-channels' and '#dma-requests' properties are unused as they are
discoverable and are non-standard (the standard props don't have '#'). So
drop them from the binding.
