nios2 - adjust gbl data off to account for bd_info 

* Adjust the GBL_DATA_OFFSET to account for the fact that we'll be
   using the space between that offset and the start of the malloc
   region to allocate both a gd structure and a board info structure.

 * This fixes a memory corruption bug due to overlap of the malloc
   region and the bd_info structure.
