[PATCH v3 5/7] arm64: dts: mediatek: cherry: Enable secondary SD/MMC controller

[AngeloGioacchino Del Regno]

As of now, all of the boards based on the cherry platform have a
usable secondary SD/MMC controller, usually for SD cards: enable
it to allow both booting from it and generally accessing external
storage.
