Eric Biggers 4b6d196c9c crypto: arm64/chacha - fix chacha_4block_xor_neon() for big endian 
The change to encrypt a fifth ChaCha block using scalar instructions
caused the chacha20-neon, xchacha20-neon, and xchacha12-neon self-tests
to start failing on big endian arm64 kernels.  The bug is that the
keystream block produced in 32-bit scalar registers is directly XOR'd
with the data words, which are loaded and stored in native endianness.
Thus in big endian mode the data bytes end up XOR'd with the wrong
bytes.  Fix it by byte-swapping the keystream words in big endian mode.
