If you open the product > page, it also suggests that. xx is a wildcard only for modules TQMa93xx, depending on the soldered SoC, but not for the mainboard MBa93xx. You are right that there is the ordering number MBa9352LA-AA, so the compatible would be "tq,imx93-tqma9352-mba9352la". But the actual values for the wildcards is copied from the soldered module. So using a TQMa9351LA would result in MBa9351LA-AA, although the mainboard is identical.
