net: axi_emac: Use reg property for DMA registers

Browse Source 
As per the xlnx,axi-ethernet-1.00.a DT documentation in linux, the AXI
DMA registers can be obtained via the reg property or via a separate
node for the axistream DMA controller. Currently only the latter is
supported, so add support to fetch the DMA controller registers from the
"reg" property.
