How about:
The first reg resource is the I/O port register block on which MDIO 
resides.  The second reg resource is the I/O port register block on 
which MDC resides.  If there is only one reg resource, it is used for 
both MDIO and MDC.

We also need to change the reference to port C in fsl,mdio-pin and 
fsl,mdc-pin.
