- Add RZ/A3M board configuration in CMakeLists.txt for both demos
- Add software rotation support for portrait displays (720x1280)
- Add touch input support with GT911 controller
- Update west.yaml to use Renesas Zephyr fork (wip_rz branch)
- Add board-specific config and overlay files

I‘m a little confused by the term software rotation here. Would it perhaps make more sense to say what the display orientation is (Landscape/Portrait)?

It seems odd to me that a variable called logicalSize is of type PhysicalSize. Do you perhaps intend to distinguish between the physical size in natural orientation and the logical size after an added rotation?
Is it necessary to cache this value or can it perhaps be computed on the fly?

Great work overall - I’m pleased to see how little additional code this requires. That said, I feel the handling of the display orientation should perhaps be cleaned up. For example by generalizing it and unconditionally setting the rotation on the software renderer.
