[PATCH] arm64: dts: imx8mp: Fix missing microSD slot vqmmc on Data Modul i.MX8M Plus eDM SBC

[Marek Vasut]

Add missing microSD slot vqmmc-supply property, otherwise the kernel
might shut down LDO5 regulator and that would power off the microSD
card slot, possibly while it is in use. Add the property to make sure
the kernel is aware of the LDO5 regulator which supplies the microSD
slot and keeps the LDO5 enabled.
