Subject: [PATCH v1 4/5] arm64: dts: imx8mq-librem5-devkit: Drop power-supply

Use a power sequence instead. As this handles the wifi disable line
rename the pincontrol accordingly. This also makes it similar to the
Librem 5.

Resolves following warning:

arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dtb: mmc@...50000: Unevaluated properties are not allowed ('power-supply' was unexpected)
        from schema $id: http://devicetree.org/schemas/mmc/fsl-imx-esdhc.yaml#
