-Xilinx Zynq FPGA Manager

-Required properties:
-- compatible:		should contain "xlnx,zynq-devcfg-1.0"
-- reg:			base address and size for memory mapped io
-- interrupts:		interrupt for the FPGA manager device
-- clocks:		phandle for clocks required operation
-- clock-names:		name for the clock, should be "ref_clk"
-- syscon:		phandle for access to SLCR registers
-
-Example:
-	devcfg: devcfg@...07000 {
-		compatible = "xlnx,zynq-devcfg-1.0";
-		reg = <0xf8007000 0x100>;
-		interrupts = <0 8 4>;
-		clocks = <&clkc 12>;
-		clock-names = "ref_clk";
-		syscon = <&slcr>;
