This is an incorrect use of the max-frequency property.
The max-frequency value limit the output clock of the mmc interface and depends on the controller, circuit (level shifter), board and so on. It doesn't represents the clock frequency of the controller.
The clock setup inside the clock framework should use the assigned-clock-rates property. The mmc driver should only enable the clock and pass the clock rate together with the max-frequency to the mmc framework.
