arm64: dts: imx8mp-var-dart-sonata: Fix Sonata SD I/O supply
LDO5 powers the USDHC2 I/O rail on DART-MX8M-PLUS.
Without a regulator consumer, the kernel disables LDO5 during late init,
which removes the SD card and causes filesystem I/O errors.
Reference LDO5 as the Sonata USDHC2 VQMMC supply, so the regulator
remains enabled while the SD interface is active.
Fixes: 41cd3d91ca859 ("arm64: dts: imx8mp-var-dart: Add support for Variscite Sonata board")
