CRIS: Export missing function symbols
strcmp was lost when all other string functions were removed, but we still have an optimized version for this on CRISv32, so any driver built as a module would not have access to this symbol. In a similar manner, we had optimized versions of csum_partial_copy_from_user and __do_clear_user but no exported symbols for them, breaking bunch of other drivers when built as a module. At the same time, move EXPORT_SYMBOL(__copy_user) and EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's located together with the function definition.
