It turns out uSD card detection on the Jetson AGX Xavier is not working and
I/Os are limited to 3.3 V. SDIO is supported but not enabled. Also, the
on-board eMMC module is using HS200 only.
Changes in v2:
- fix board name in commit messages
- rebase on for-next
Kind regards,
Tamas

Add pad voltage configuration nodes for SDMMC pads with configurable voltages
and enable supported SD card, SDIO and eMMC modes.
