arm64: dts: rockchip: remove orphaned pinctrl-names from pinephone pro

The patch adding display support for the pinephone pro introduced two
regulators that contain pinctrl-names props but no pinctrl-assignments.

Looks like someone forgot the pinctrl settings, so remove the orphans
for now, until that changes.
