arm64: dts: imx8mp-tqma8mpql: fix LDO5 power off
Fix SD card removal caused by automatic LDO5 power off after boot:
LDO5: disabling
mmc1: card 59b4 removed
EXT4-fs (mmcblk1p2): shut down requested (2)
Aborting journal on device mmcblk1p2-8.
JBD2: I/O error when updating journal superblock for mmcblk1p2-8.
To prevent this, add vqmmc regulator for USDHC, using a GPIO-controlled
regulator that is supplied by LDO5. Since this is implemented on SoM but
used on baseboards with SD-card interface, implement the functionality
on SoM part and optionally enable it on baseboards if needed.
