Revert "dt-bindings: pinctrl-zynqmp: Add output-enable configuration"

This reverts commit 133ad0d.

On systems with older PMUFW (Xilinx ZynqMP Platform Management Firmware)
using these pinctrl properties can cause system hang because there is
missing feature autodetection.
When this feature is implemented, support for these two properties should
bring back.
