drm: shmobile: use vblank hooks in struct drm_crtc_funcs
The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead. As the result, shmob_drm_crtc_enable_vblank() becomes a static function, although it gets moved around a bit to save forward declaration.
