Fix SD card removal caused by automatic LDO5 power off after boot

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.
