CFI Byte order problem

[Mori Hiroki]

Hi.

I build Current for AR9132. But don't recognize cfi flash memory.
I make debug write and found byte endian issue. I seem AR9132
is byte swap in cfi flash memory by default. Current cif code is 
byte swap on Big Endian machine. This is conflict.

I make workaound by option for this problem.
