If CONFIG_USE_ARCH_MEMCPY is selected, let's use the assembly optimized
memcpy implementation for the 'cp' command.
Currently only Blackfin uses memcpy for the 'cp' command, so extend
this to the CONFIG_USE_ARCH_MEMCPY users.
Tested on a mx6qsabreauto board where a 5x gain in performance is seen
when reading 10MB from the parallel NOR memory.

Sending as RFC as I don't know if any extra checks would be required here,
so I appreciate any feedback.
