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.
