mxs: mxsboot: fix endianess for sd boot images
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.
