When using CSC adjustment the CM remap is set to bypass and MPCC remap is used. However to bypass CM some state in the context is modified and not restored correctly resulting in subsequent calls to disable MPCC remap as well. [How] Fix logic for save/restore of remap enable flag when programming MPCC remap matrix.
