The fact that all supported boards use the same 33MHz crystal is a co-incidence. The Zynq PS support a range of crystal freqs so the hardcoded setting should be removed from the dtsi. Re-implement it on the board level. This prepares support for Zynq boards with different crystal frequencies (e.g. the Digilent ZYBO).
