[PATCH] dt-bindings: pinctrl: pincfg-node: permit bias-high-impedance with other bias properties

[Conor Dooley]

From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

It is possible that devices tristate buffers may set the buffer to
the high-Z state in addition to setting pull-up or pull-down on a pin.
Remove this particular restriction to prevent warning on zynqmp systems
where this configuration seems to be valid.
