drm/simple_kms_helper: Add {enable|disable}_vblank callback support
If simple_kms_helper based driver needs to work with vblanks, then it has to provide drm_driver.{enable|disable}_vblank callbacks, because drm_simple_kms_helper.drm_crtc_funcs does not provide any. At the same time drm_driver.{enable|disable}_vblank callbacks are marked as deprecated and shouldn't be used by new drivers. Fix this by extending drm_simple_kms_helper.drm_crtc_funcs to provide the missing callbacks.
