1.9.1
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.

Add a DTS describing the Digilent ZYBO board. Similar to ZED but with
a 50MHz crystal instead of 33MHz.

Hi Peter,
The patches look all good to me. But you may want to check your CC
lists. I think at least the DT list should be included.
For the whole series:
