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).

Due to dependencies between timer and CPU frequency, only changes by
