Subject: [PATCH 2/4] arm64: dts: qcom: sm7225-fairphone-fp4: Add camera
 EEPROMs

Add notes for the EEPROMs found on the main rear camera, ultra-wide rear
camera and front camera. Also add some comments that act as placeholders
for other nodes that will be added in the future, for the camera sensors
and some VCM drivers.
