Will be needed once we call of_clk_set_defaults() from the driver core.

So far we only honour the assigned-clocks and assigned-clock-rates
device tree properties for the clock controller nodes. With this patch
we also honour the properties for each device which is done by Linux
as well.

This breaks the default barebox console on the i.MX7 sabresd.
The default UART, uart1, specifies assigned-clock-parents, which is now applied
and causes garbage to be output on the serial port.
&uart1 {
/delete-property/ assigned-clocks;
/delete-property/ assigned-clock-parents;
};
Fixes it, but I didn't dig deeper than that.

Care to send this as a patch so that we at least have a stop gap
solution?

Sure. Working on it now. Don't tag the new release just yet :D
