microblaze: Fix unaligned value saving to the stack for system with MMU
Several registers weren't saved correctly to the stack. Unaligned expection for system with MMU stores value in ex_tmp_data_loc_X address which is load to registers r3. The next step is to move this value from r3 to a destination register which caused unaligned exception. For several registers this value was directly moved to the register. For example for r28: by "or r28, r0, r3" but register r28 was rewritten when kernel returns from exception handler by value saved on stack. This patch changed r3 saving to the correct address on the stack. For example for r28: by "swi r3, r1, 4 * 28" When kernel returns from the exception handler, correct value is restored.
