Nope. First of all, pinctrl usage is with pinctrl-N properties, not the pinctrl device, and there are no defaults set for any of the mmc nodes. Second, these are board design specific. For example, boards are free to use just 4 bits for the eMMC if they so desire. So this should be in each board dts file. If a board is missing this property, fix the board. This applies to all three patches in the series.
