Someone was complaining about the usdhc clock assignment in soc.dtsi, because some
usdhc nodes are having clock assignments while some are NOT. That is why I did this
patch set. I agree that we can have default settings in soc.dtsi, so do you think it makes
sense to add default clock assignment to all usdhc nodes? If yes, I will redo the patch
set.

Thanks,
Anson.
