yuehongwu e5504ab2cd hygon: The feature of Hygon SSE2 accelerated memory copy is disabled by default. 
nt_cpy_mini_len is used by get_nt_block_copy_mini_len function，and return
to nt_blk_cpy_mini_len variable. nt_blk_cpy_mini_len will be used in
arch/x86/include/asm/uaccess_64.h, if it is 0, kernel will not call
copy_user_large_memory_generic_string function.
