[PATCH V2 2/3] arm: dts: zynq: Move crystal freq. to board level

[Peter Crosthwaite]

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).

Changed since v1:
Alphabetize node ordering (Soren review)

Im guessing long term this should be converted to a fixed clock. But
I think this at least steps in that direction.
