From 485ff2cab884dc2fa30d115411f4e84c3e3378bf Mon Sep 17 00:00:00 2001
From: Tom Lendacky <thomas.lendacky@amd.com>
Date: Tue, 3 Jul 2018 12:11:52 -0500
Subject: [PATCH 123/131] crypto: ccp - Remove unused #defines
Remove some unused #defines for register offsets that are not used. This
will lessen the changes required when register offsets change between
versions of the device.
