We hardcode the pinctrl setting for the MMC controllers in boards.c, since we need them also in the SPL, where there is no DT yet. Add the respective setting for the H616 SoC, to enable eMMC on boards with this SoC as well. Also to make diagnosing this problem easier, print a warning if a board tries to setup MMC2 pins without a respective SoC setting being defined.
