RMI4 is often implemented on in-cell panels which require tight power
seqeuncing. The kernel way to approach that is the panel_follower API.

This series adds that in the RMI4 driver and wires it up on a
Snapdragon 845-based Sony Xperia XZ2, also resolving the DT warnings
stemming from the current hack.
