[PATCH V3 3/3] arm64: dts: imx8mp: Enable HS400-ES

[Adam Ford]

The SDHC controller in the imx8mp 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.
