[PATCH v2 4/4] ARM: dts: pxa: use new 'dma-channels/requests' properties

[Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>]

The '#dma-channels' and '#dma-requests' properties were deprecated in
favor of these defined by generic dma-common DT bindings.  Add new
properties while keeping old ones for backwards compatibility.
