Subject: [PATCH V3 2/3] arm64: dts: imx8mn: Enable HS400-ES
Date:   Sat,  2 Apr 2022 14:39:40 -0500

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.

V3:  Keep the fsl,imx7d-usdhc to keep backwards compatiblity and prevent breaking something.
