commit a45dde2293c816138e53c26eca6fd0322583f9a6 changed the dm9000 direct register access to standard IO. This should work on the ColdFire platform as there are corresponding macros for the LE devices. But the hardware settings on M5253DEMO board had swapped the byte order which make the original macros such as out_le16 cannot work. To avoid changing the common io access code on ColdFire platform, the DM9000_BYTE_SWAPPED define added to make the dm9000 use __raw* IO access on ColdFire M5253DEMO board.
