drm/privacy_screen: Add drvdata in drm_privacy_screen Allow a privacy screen provider to stash its private data pointer in the drm_privacy_screen, and update the drm_privacy_screen_register() call to accept that. Also introduce a *_get_drvdata() so that it can retrieved back when needed. This also touches the IBM Thinkpad platform driver, the only user of privacy screen today, to pass NULL for now to the updated API.
