v2 cover Add VMX module for PPC64

VMX cryptographic acceleration instructions were added to the POWER8 CPU. These instructions implement portions of AES and GHASH in hardware.

This patch set adds a new module for PPC64, vmx, that support cryptographic routines such as AES and GHASH on hardware. In order to access VMX instructions on Power 8 CPU this module uses scripts implemented in colaboration with OpenSSL.

Changelog[v2]
1. Patch style fixes
2. Redo unecessary conditions on drivers/crypto/Kconfig and vmx/Makefile in previous [Patch 7/7]
