[PATCH] dt-bindings: spi: zynqmp-qspi: Include two 'reg' properties only for the Zynq UltraScale QSPI

[Amit Kumar Mahapatra <amit.kumar-mahapatra@xxxxxxx>]

Linear mode is only supported by the Zynq UltraScale QSPI controller,
so update the bindings to include two 'reg' properties only for the
Zynq UltraScale QSPI controller.
