[U-Boot] [PATCH v2] post, memorytest: add support for none powerpc archs

[Heiko Schocher]

change bd->bi_memsize to gd->ram_size, as this is defined
on all archs, so this post test can used on none powerpc
archs too.

changes for v2:
  added comment from Wolfgang Denk:
    - add comment, that this function is only valid
      for contiguous memory banks.
  added comment from Mike Frysinger:
    - use gd->ram_size instead of bd->bi_memsize
      -> no ifdef needed.
