The patch updates the booting-without-of.txt-file.
There is a description for the case
if mdio data and clock pins are on different processor ports.
It extends the "[PATCH v3] using mii-bitbang on different processor ports".

Properties for fsl,cpm2-mdio-bitbang:
- fsl,mdio-pin : pin of port C controlling mdio data
- fsl,mdc-pin : pin of port C controlling mdio clock
