  MFp4:
  
  For 32-bit SDRAM systems, enable D16 to D31 in the PIO controller.
  Otherwise they read back as 0xffff.
  
  Shave 8 bytes from the object size by using AT91C_BASE_PIOA directly
  and by not assigning PIO_BSR to 0 in the DBGU init.  That's a nop in
  two ways (everything defaults to peripheral A, and writing 0 changes
  nothing).
