dt-bindings: arm: arm,coresight-static-replicator: add optional clocks

As most other CoreSight devices the replicator can use either of the
optional clocks. Document those optional clocks in the schema.
Additionally document the one-off case of Zynq-7000 platforms which uses
apb_pclk and two additional debug clocks.
