3.16.7-ckt13 -stable review patch. If anyone has any objections, please let me know.

From: Philippe Reynes <tremyfr@gmail.com>
commit a29ef819f3f34f89a1b9b6a939b4c1cdfe1e85ce upstream.
According to the imx27 documentation, fec has a 4 Kbyte memory space map. Moreover, the actual 16 Kbyte mapping overlaps the SCC (Security Controller) memory register space. So, we reduce the memory register space to 4 Kbyte.
