This patch series enable an accelerated AES/GCM stitched implementation
for Power10 or later CPU(ppc64le). This module supports AEAD algorithm.
The stitched implementation provides 3.5X+ better performance than the
baseline.

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.
