[PATCH 3/4] dt-bindings: pinctrl-zynqmp: Add output-enable configuration

Add 'output-enable' configuration parameter to the properties list.

Using these pinctrl properties observed hang issues with older Xilinx
ZynqMP Platform Management Firmware, hence reverted the patch previously.

output-enable configuration"").
