[U-Boot] [PATCH 14/34] Blackfin: fix bd_t handling

[Mike Frysinger]

The recent global data changes (making the size autogenerated) broke the
board info handling on Blackfin ports as we were lying and lumping the
bd_t size in with the gd_t size.  So use the new dedicated bd_t size to
setup its own address in memory.
