If present, sources the fec's PTP clock straight from
the enet PLL, instead of having to be routed via a SoC pad.
This is only possible on certain SoCs, notably the imx6 (quad) plus.

tx/rx queues 1 and 2. "int0" will be used for queue 0 and ENET_MII interrupts.
For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse
per second interrupt associated with 1588 precision time protocol(PTP).
