microblaze: usable uart16550 for big endian systems
As a result of the commit 6833260 the uart16550 driver is broken for Microblaze big endian systems, because of the missing 3 byte offset. Other than as described, not all U-Boot BSP will treat properly the 3 byte offset. This why prefer to mask out the 3 byte offset in general and setup correct _REG_SIZE value depending on edianess.
