Fix data mismatch over ipsec tunnel encrypted/decrypted with ppc64le AES/GCM module. This patch is to fix an issue when simd is not usable that data mismatch may occur. The fix is to register algs as SIMD modules so that the algorithm is excecuted when SIMD instructions is usable. A new module rfc4106(gcm(aes)) is also added. Re-write AES/GCM assembly codes with smaller footprints and small performance gain. This patch has been tested with the kernel crypto module tcrypt.ko and has passed the selftest. The patch is also tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled.
