Subject: [PATCH] mb/asrock/b85m_pro4: Factor out common MRC settings

These settings are the same on all boards. Since the other boards
currently overwrite the struct contents, it doesn't make a difference.
To ease review, the same settings will be dropped from other boards in
separate commits, one board at a time.
