This is a first stab at adding serdes support on the LS1088A. Linux hangs around when the serdes is initialized if the si5341 is enabled, so it's commented out. The MC firmware needs to be fairly new (it must support DPAA2_MAC_FEATURE_PROTOCOL_CHANGE), and the DPC needs to set the macs to MAC_LINK_TYPE_BACKPLANE. For this reason, I think this will be difficult to do in a backwards-compatible manner. I have not really tested this, but hopefully it can be a good starting point.
