Fix a doorbell race on Cortex-A78AE where the compiler reorders a 64-bit WQE load before the 32-bit stores that construct it, causing stale data to reach the hardware doorbell. The first patch fixes the root cause by passing a pointer and adding a compiler barrier; The second patch reverts the crypto march extension workaround that is no longer needed and that broke builds without AES support.
