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



Add support to handle 'output-enable' and 'bias-high-impedance'
configurations.

Using these pinctrl properties observed hang issues with older PMUFW(Xilinx
ZynqMP Platform Management Firmware), hence reverted the patch.
Commit 9989bc33 ("Revert "pinctrl: pinctrl-zynqmp: Add support
for output-enable and bias-high-impedance"").

Support for configuring these properties added in PMUFW Configuration Set
version 2.0. When there is a request for these configurations from pinctrl
driver for ZynqMP platform, xilinx firmware driver checks for this version
before configuring these properties to avoid the hang issue and proceeds
further only when firmware version is >=2 otherwise it returns error.
