AMD DCN 4.01 display GPIO helpers

A small set of internal helper files inside AMD's Display Core (DC) code that handle GPIO pin programming for the DCN 4.01 display block found in recent Radeon and Ryzen integrated graphics. It is part of the larger amdgpu DRM driver rather than something users load on its own.

recommendation

This is not actually a standalone driver; it is a hardware-generation-specific subfolder of the AMD Display Core inside the amdgpu graphics driver, providing GPIO plumbing for the DCN 4.01 display engine. It only makes sense as part of the larger amdgpu module and should not be evaluated for keep/remove on its own.

codex reasoning notes (technical)

Not a driver directory: DCN401-specific AMD display-core GPIO helper subdirectory inside DRM, with no standalone kernel device driver entry point.
