Subject: [RFC PATCH 7/9] arm: dts: dra: Add dma-request crossbar phandle to dma-specs

The dma-request lines from peripherals are connected to
the dma-controller through a crossbar router. Adding this
crossbar phandle to the peripheral's dma-specs. This is
used by the driver to identify the router associated with
a dma-request line and map it.
