Not sure if we shouldn't be more specific about the fact the entries in
the clocks property must be in same order as names in clock-names. Perhaps
it's sufficient you mentioned the common clock binding which defines that.

Also we should keep the clock names same, regardless which MFC IP version
those apply to. At least as far as same driver is used for them and the
number of clocks is same. Thus perhaps this could be:

- clock-names : from common clock binding: must contain "sclk_mfc" and "mfc",
	corresponding to entries in the clocks property.

Please note there is a white space before the first colon, that makes
it really an important improvement...
