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

This reverts commit 123462e5e534d6e17b1b7d2006734bbe54b03e0a.

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.
