dt-bindings: clock: xilinx: Convert VCU bindings to dtschema

Convert AMD (Xilinx) VCU bindings to yaml format.
Additional changes:
   - move xlnx_vcu DT binding to clock from soc following commit
     a2fe7baa27 ("clk: xilinx: move xlnx_vcu clock driver from soc")
   - corrected clock sequence as per xilinx device-tree generator

LogicoreIP designed compatible with Xilinx ZYNQ family.
-------------------------------------------------------
General concept
---------------
LogicoreIP design to provide the isolation between processing system
and programmable logic. Also provides the list of register set to configure
the frequency.
Required properties:
- compatible: shall be one of:
"xlnx,vcu"
"xlnx,vcu-logicoreip-1.0"
- reg : The base offset and size of the VCU_PL_SLCR register space.
- clocks: phandle for aclk and pll_ref clocksource
- clock-names: The identification string, "aclk", is always required for
the axi clock. "pll_ref" is required for pll.
Example:
xlnx_vcu: vcu@a0040000 {
compatible = "xlnx,vcu-logicoreip-1.0";
reg = <0x0 0xa0040000 0x0 0x1000>;
clocks = <&si570_1>, <&clkc 71>;
clock-names = "pll_ref", "aclk";
};
