[ Upstream commit c954b252dee956d33ee59f594710af28fb3037d9 ]
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. Called
gcm_update() to generate the final digest if needed.
A new module rfc4106(gcm(aes)) is also added.
Fixes: cdcecfd9991f ("crypto: p10-aes-gcm - Glue code for AES/GCM stitched implementation")
