[PATCH 4/4] arm64: dts: qcom: sdm632-fairphone-fp3: Enable display and GPU

Add the description for the display panel found on this phone. Unfortunately the LCDB module on PMI632 isn't yet supported upstream so we need to use a dummy regulator-fixed in the meantime. And with this done we can also enable the GPU and set the zap shader firmware path.
