mxs: mxsboot: fix endianess for sd boot images

Browse source 
Running mxsboot on a big-endian system produces a sd image which
cannot be started by the i.MX28 ROM. It complains on the debug
uart as following:
0x8020a009
          0x80502008
0x8020a009
          0x80502008
...

Enforcing all fields within the BCB to little-endian make
the image bootable again.
