It is described in the arm/boot/dts/r8a77xx-aa104xd12-panel.dtsi file as a direct child of the DT root node. This allows including r8a77xx-aa104xd12-panel.dtsi in board device trees, with other minor modifications, to enable the panel. This is however not how external components should be modelled. Instead of modifying the board device tree to enable the panel, it should be compiled as a DT overlay, to be loaded by the boot loader. Prepare the r8a77xx-aa104xd12-panel.dtsi file for this usage by declaring a panel node only, without hardcoding its path. Overlay sources can then include r8a77xx-aa104xd12-panel.dtsi where appropriate. This change doesn't cause any regression as r8a77xx-aa104xd12-panel.dtsi is currently unused. As overlay support for this panel has only been tested with Gen3 hardware, and Gen2 support will require more development, move the file to arch/arm64/boot/dts/renesas/.
