Subject: [PATCH 1/2] crypto: hisilicon/zip - add lz4 and lz77_only to algorithm sysfs

The current hisilicon zip supports the new algorithms lz77_only and
lz4. To enable user space to recognize the new algorithm support,
add lz77_only and lz4 to the sysfs. Users can now use the new
algorithms through uacce.
