a recent FEC binding document update that was motivated by i.MX
development revealed that ARM and PowerPC implementations in Linux
did not agree on the clock names to use for the FEC nodes
update the FEC (fast ethernet controller) binding to document the
"per" clock name as an obsolete alias for "ipg"

this patch depends on "dt/bindings: fsl-fec: add clock properties"
by Shawn Guo which introduces the context of this patch
the patch only is necessary if the MPC5121 .dtsi update (switch
FEC nodes from "per" to "ipg") won't make it for v3.14
