Sai Krishna Potthuri ff8356060e Revert "dt-bindings: pinctrl-zynqmp: Add output-enable configuration" 
This reverts commit 133ad0d9af99bdca90705dadd8d31c20bfc9919f.

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.

Please refer to pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices, including the meaning of the
phrase "pin configuration node".
ZynqMP's pin configuration nodes act as a container for an arbitrary number of
subnodes. Each of these subnodes represents some desired configuration for a
pin, a group, or a list of pins or groups. This configuration can include the
mux function to select on those pin(s)/group(s), and various pin configuration
parameters, such as pull-up, slew rate, etc.
Each configuration node can consist of multiple nodes describing the pinmux and
pinconf options. Those nodes can be pinmux nodes or pinconf nodes.
The name of each subnode is not important; all subnodes should be enumerated
and processed purely based on their content.
