clock-frequency = <200000000>; // filled in by
boot-loader
Is better readable and makes clear that the value is filled in by the
boot loader. Usually we specify "<0>" in that case but it will *not*
work with your board because U-Boot fills into the property "clock_freq"
the CCB-frequency, which is twice as much. This needs to be fixed.

See above.
