arm64: dts: imx8mp: Fix missing microSD slot vqmmc on DH electronics i.MX8M Plus...

[ Upstream commit c53cf8ce3bfe1309cb4fd4d74c5be27c26a86e52 ]

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.
