cam: drm: Skip DRM devices not capable of mode setting
The DRM helper picks the first DRM card that it can open. On platforms that have a standalone GPU, this risks selecting a device corresponding to the GPU instead of the display controller. Fix this by skipping devices that don't support the KMS mode setting API. Some legacy display controllers would be skipped as well, but libcamera doesn't run on those systems anyway.
