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.
Commit ff8356060e3a5e126abb ("Revert "dt-bindings: pinctrl-zynqmp: Add
output-enable configuration"").
Support for configuring these properties added in Xilinx ZynqMP Platform
Management firmware(PMUFW) Configuration Set version 2.0. Linux firmware
driver checks if the configuration is supported by the PMUFW when it gets
request for TRISTATE configuration from pinctrl driver. If it supports,
then calls will be made otherwise it returns error.
