dt-bindings: clock: xilinx: describe whether dynamic reconfig is enabled 



Xilinx clocking wizard IP core's dynamic reconfiguration support is
optionally enabled at build time. Add a devicetree boolean property to
describe whether the hardware supports this feature or not.

Since dynamic reconfiguration support was previously assumed enabled,
introduce a property to indicate the inverse, in order to maintain
devicetree backwards compatibility. Hence, this new xlnx,static-config
property should be specified when dynamic reconfiguration support is
disabled in the IP core configuration.
