drm/sun4i: call drm_vblank_init with correct number of crtcs
If we want to have vblank on both pipelines at the same time, we need to call drm_vblank_init with num_crtcs = 2. Instead, since the crtc init calls correctly set mode_config.num_crtc, we can move the drm_vblank_init call to after the crtc init code is called, which is the component bind part. Then we can just pass mode_config.num_crtc in. Signed-off-by:Chen-Yu Tsai <wens@csie.org> Signed-off-by:
