mmc_of_parse() in U-Boot is a pussy helper; it sets cfg->f_max to
52MHz even if DT does not provide "max-frequency" at all. This can
overwrite cfg->f_max that may have been set to a reasonable default.
As the DT binding says, "max-frequency" is an optional property.
Do nothing if DT does not specify it. This is the behavior of
mmc_of_parse() in Linux.
