dt-bindings: net: fec: add pps channel property

commit 1aa772b upstream. Add fsl,pps-channel property to select where to connect the PPS signal. This depends on the internal SoC routing and on the board, for example on the i.MX8 SoC it can be connected to an external pin (using channel 1) or to internal eDMA as DMA request (channel 0).
