arm64: dts: qcom: sdm632-fairphone-fp3: Enable display and GPU

Browse Source 
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.
