PATCH 1/1 arm64: dts: imx8mp-verdin: Label ldo5 and link to usdhc2

From: Philippe Schenker <[email protected]>

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.
