Subject: [RFC PATCH 9/9] arm: dts: dra7: Change the total dma-req numbers to crossbar channels

On DRA7 there is a crossbar router which maps the peripheral
dma request channels to the dma controller inputs. The
dma-controller can receive requests from any of the crossbar
channels. So register the total number crossbar channels instead
of the shared dma-request lines.
