Subject: crypto: arm64/aes-neonbs - switch to library version of key expansion
 routine
Patch-mainline: v5.4-rc1
Git-commit: f68df54307aaae01df66977511ea719158201188
References: jsc#SLE-15129

Switch to the new AES library that also provides an implementation of
the AES key expansion routine. This removes the dependency on the
generic AES cipher, allowing it to be omitted entirely in the future.
