drm/rockchip: vop2: Remove prepare_fb/cleanup_fb callback

Browse Source 
According to commit 9bde4e671f ("drm/rockchip: vop: fix iommu crash
with async atomic")
These two callback were added to avoid iommu crash on async
commit caused by drm_atomic_clean_old_fb after drm_atomic_async_commit.

drm_atomic_clean_old_fb was removed after commit
e00fb8564e ("drm: Stop updating plane->crtc/fb/old_fb on atomic drivers")

So we can remove them to make life  simpler.
