MIPS: start.S: fix boundary check in relocate_code
The loop code copies more data with one than
necessary due to the 'ble' instuction. Use the
'blt' instruction instead to fix that.
Due to the lack of suitable hardware the Xburst
specific code is compile tested only. However the
change is quite obvious.
