From: Philippe Schenker <philippe.schenker@xxxxxxxxxxxx> 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.
