microblaze: Fix ASM optimized code for LE
Microblaze little-endian doesn't support ASM optimized library functions(memcpy/memmove). Kconfig doens't contain any information about endian that's why it is necessary to check it in the source code. The code is used with barrel shifter is used. Signed-off-by: Michal Simek <monstr@monstr.eu>
