microblaze: Remove "cache" optimized copy_page function
Current implementation doesn't handle dcache_line_length correctly that's why is better to use generic memcpy. Cache optimized function could be good way howto improve performance but must be based on benchmarking not blind function like this. Signed-off-by: Michal Simek <monstr@monstr.eu>
