Subject: [PATCH 2/4] crypto: arm64/sm4-ce - rename to sm4-ce-cipher

The subsequent patches of the series will have an implementation
of SM4-ECB/CBC/CFB/CTR accelerated by the CE instruction set, which
conflicts with the current module name. In order to keep the naming
rules of the AES algorithm consistent, the sm4-ce algorithm is
renamed to sm4-ce-cipher.

In addition, the speed of sm4-ce-cipher is better than that of SM4
NEON. By the way, the priority of the algorithm is adjusted to 300,
which is also to leave room for the priority of SM4 NEON.
