arm64: dts: qcom: sm7225-fairphone-fp4: Enable display and GPU

Add the description for the display panel found on this phone.
Unfortunately the LCDB module on PM6150L 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.
