UPSTREAM: crypto: arm64/chacha - fix hchacha_block_neon() for big endian
On big endian arm64 kernels, the xchacha20-neon and xchacha12-neon
self-tests fail because hchacha_block_neon() outputs little endian words
but the C code expects native endianness. Fix it to output the words in
native endianness (which also makes it match the arm32 version).
