microblaze: Don't use access_ok for unaligned
it assumes we have an unaligned exception handler which (a) may not be true (b) costs a lot of performance Instead we'll use struct/union method for big endian accesses, and byte-shifting for little endian. Signed-off-by: John Williams <john.williams@petalogix.com>
