Paulo Flabiano Smorigo 11c6e16ee1 crypto: vmx - Adding asm subroutines for XTS
This patch add XTS subroutines using VMX-crypto driver.

It gives a boost of 20 times using XTS.

These code has been adopted from OpenSSL project in collaboration
with the original author (Andy Polyakov <appro@openssl.org>).
