Since the watermark registers arent double buffered on VLV/CHV, we'll need to play around with intermediate watermarks same was as we do on ILK-BDW. The watermark registers on VLV/CHV contain inverted values, so to find the intermediate watermark value we just take the minimum of the active and optimal values. This also means that, unlike ILK-BDW, there's no chance that we'd fail to find a working intermediate watermarks. As long as both the active and optimal watermarks are valid the intermediate watermarks will come out valid as well. Signed-off-by:
