[PATCH V4 2/3] arm64: dts: imx8mn: Enable HS400-ES

From: Adam Ford
Date: Sun Apr 10 2022 - 15:36:33 EST


The SDHC controller in the imx8mn has the same controller
as the imx8mm which supports HS400-ES. Change the compatible
fallback to imx8mm to enable it, but keep the imx7d-usdhc
to prevent breaking backwards compatibility.

V4: No Change
V3: No change
V2: Keep fallback to fsl,imx7d-usdhc to prevent breakage
