Some cleanups and optimizations for the arm64 AES skcipher routines. Patch #1 fixes the peculiar use of u8 arrays to refer to AES round keys, which are natively arrays of u32. Patch #2 partially reverts the use of NEON yield calls, which is not needed for skciphers. Patch #3 adds support for cts(cbc(aes)) in the NEON chaining mode handling. Patch #4 tweaks the XTS handling to remove a literal load from the inner loop.
