Revert "pinctrl: zynqmp: Add support for output-enable and bias-high-impedance"

Browse source 
This reverts commit 123462e5e5.

On systems with older PMUFW using these pinctrl properties can cause system
hang because there is missing feature autodetection.
When it is implemented support for these two properties should go back.
