Add PPC64LE assembly for AES-GCM.
This change adds AES and GHASH assembly from upstream, with the aim of
speeding up AES-GCM.
The PPC64LE assembly matches the interface of the ARMv8 assembly so I've
changed the prefix of both sets of asm functions to be the same
("aes_hw_").
Otherwise, the new assmebly files and Perlasm match exactly those from
upstream's c536b6be1a (from their master branch).
