mmc: bcm2835-mmc: Support underclocking

Support underclocking of the SD bus using the max-frequency DT property
(which currently has no DT parameter). The sd_overclock parameter
already provides another way to achieve the same thing which should be
equivalent in end result, but it is a bug not to support max-frequency
as well.

See: https://github.com/raspberrypi/linux/issues/2350
