[PATCH 2/3] dts: mpc512x: adjust clock specs for FEC nodes

[Gerhard Sittig <gsi-ynQEQJNshbs@public.gmane.org>]

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

change clock names from "per" to "ipg" in the FEC nodes of the
mpc5121.dtsi include file such that the .dts specs comply with
the common FEC binding

this "incompatible" change does not break operation, because
- COMMON_CLK support for MPC5121/23/25 and adjusted .dts files
  were only introduced in Linux v3.14-rc1, no mainline release
  provided these specs before
- if this change won't make it for v3.14, the MPC512x CCF support
  provides full backwards compability, and keeps operating with
  device trees which lack clock specs or don't match in the names
