crypto: chacha20 - Use unaligned access macros when loading key and IV
The generic ChaCha20 implementation has a cra_alignmask of 3, which
ensures that the key passed into crypto_chacha20_setkey() and the IV
passed into crypto_chacha20_init() are 4-byte aligned. However, these
functions are also called from the ARM and ARM64 implementations of
ChaCha20, which intentionally do not have a cra_alignmask set. This is
broken because 32-bit words are being loaded from potentially-unaligned
buffers without the unaligned access macros.
Fix it by using the unaligned access macros when loading the key and IV.
