arm64: dts: zynqmp: Add mode-pin GPIO controller DT node

Add mode-pin GPIO controller DT node in zynqmp.dtsi and wire it to usb0
controller. All Xilinx evaluation boards are using modepin gpio for ULPI
reset that's why wire it directly in zynqmp instead of c&p the same line to
every board specific file.
