This Xilinx clocking wizard IP core outputs this interrupt signal to
indicate when one of the four optional user clock inputs is either
stopped, overruns, underruns or glitches.

This functionality was only added from version 6.0 onwards, so restrict
it to particular compatible strings.

v1 -> v2: Fix binding errors by moving interrupts up front, restrict later

Why multiple blank lines? Only one.

With above fixed:

There were two blank lines here previously. I assumed it may have been to
separate out the vendor specific properties. Will remove in v3.
