Subject: [PATCH 2/2] arm64: dts: imx8mm: Correct OPP table according to latest datasheet

From: Anson Huang <Anson.Huang@....com>

According to latest datasheet (Rev.0.2, 04/2019) from below links,
1.8GHz is ONLY available for consumer part, so the market segment
bits for 1.8GHz opp should ONLY available for consumer part accordingly.
