dt-bindings: mmc: arasan,sdci: Add gate property for Xilinx platforms
Add gate property in example node for Xilinx platforms which will be used
to ungate the DLL clock. DLL clock is required for higher frequencies like
50MHz, 100MHz and 200MHz.
DLL clock is automatically selected by the SD controller when the SD
output clock frequency is more than 25 MHz.
