[PATCH v1] arm64: dts: imx8mp-verdin: Label ldo5 and link to usdhc2

[Philippe Schenker]

From: Philippe Schenker <philippe.schenker at impulsing.ch>

This commit labels LDO5 as `reg_vdd_sdio` in `imx8mp-verdin.dtsi` to
facilitate changing its voltage to 1.8V, necessary for an SDIO
peripheral that requires 1.8V at default and high-speed modes.

Additionally, it links `reg_vdd_sdio` to `&usdhc2`, aligning with the
hardware configuration specified in the datasheet.
