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.
