ARM: DTS: am33xx: Use the new DT bindings for the eDMA3
Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3 and enable the DMA even crossbar with ti,am335x-edma-crossbar. With the new bindings boards can customize and tweak the DMA channel priority to match their needs. With the new binding the memcpy is safe to be used since with the old binding it was not possible for a driver to know which channel is allowed to be used as non HW triggered channel.
