CVE-2026-98782: drm/mediatek: Fix ovl adaptor platform device leak

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Fix ovl adaptor platform device leak mtk_drm_probe() creates an OVL adaptor platform device with platform_device_register_data() when the display pipeline requires the OVL adaptor. If a later initialization step fails, the probe error path releases the DRM resources without unregistering the already registered OVL adaptor device. The normal remove path likewise leaves the device registered after the DRM driver is unbound. Keep track of whether the OVL adaptor was successfully registered and unregister it on probe failure. Also recover the platform device from the stored DDP component device and unregister it during normal removal. The issue was identified by a static analysis tool I developed and confirmed by manual review.
