microblaze: Add support for little-endian Microblaze Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization.

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.
