This is ultimately setting the "f_max" ("maximum operating frequency")
field in the MMC core, so I'm happy naming the property "max-frequency".

It's true that this doesn't explain the derivation to clock rate --
but we weren't doing that before the DT binding either, and I think that
having a discrepancy between the DT property and the core's naming would
lead to confusion/mistakes.
