[PATCH v3] imx27: dt: only map 4 Kbyte for fec registers

[Philippe Reynes]

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.
