Add devicetree overlay for the Seeed Studio BeagleBone HDMI cape, which
provides HDMI output via an ITE IT66121 HDMI bridge and audio support
through McASP.

https://www.seeedstudio.com/Seeed-Studio-BeagleBoner-Green-HDMI-Cape.html

This overlay requires the recent tilcdc cleanup patch series that was merged
to drm-misc-next to function properly:
https://lore.kernel.org/lkml/20260123-feature_tilcdc-v5-0-5a44d2aa3f6f@bootlin.com/ (local)

With this DRM tree dependency I don't know if this series should land in
DRM tree or in OMAP tree.
