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.

- map 4 Kbyte instead of 1 Kbyte
v3:
- point that actual fec mapping overlap scc mapping (I forget it in v2)
