dpaa_eth: change DMA device
The DPAA Ethernet driver is using the FMan MAC as the device for DMA
mapping. This is not actually correct, as the real DMA device is the
FMan port (the FMan Rx port for reception and the FMan Tx port for
transmission). Changing the device used for DMA mapping to the Fman
Rx and Tx port devices.
