ARM: dts: imx27: only map 4 Kbyte for fec registers
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.
