Subject: [PATCH 3/3] crypto: qce: add support for QCE major version 6

From: Gaurav Kashyap <gaurav.kashyap@....qualcomm.com>

The Qualcomm General Purpose Crypto Engine (GPCE) has
upgraded to version 6 on newer socs, this makes the
version check logic obsolete and needs to be updated
to account for v6.0.

As part of this, unnecessary version macros has also
been removed.
