Subject: [PATCH] arm64: dts: imx8mm-verdin: Link reg_nvcc_sd to usdhc2

Link LDO5 labeled reg_nvcc_sd from PMIC to align with
hardware configuration specified in the datasheet.

Without this definition LDO5 will be powered down, disabling
SD card after bootup. This has been introduced in commit
f5aab0438ef1 (regulator: pca9450: Fix enable register for LDO5).

Fixes: f5aab0438ef1 (regulator: pca9450: Fix enable register for LDO5)
