arm: dts: zynq: Move crystal freq. to board level
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).
