Michal Simek 43f2a6e8b1 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.
