We should not cleanup iommu before cleanup other resources.

Reorder unload sequence, follow exynos drm.

This doesn't match the cleanup sequence in rockchip_drm_bind. Also make sure
that you're unwinding the setup sequence when you cleanup (ie: take a close look
at how you set things up and reverse it for cleanup).
ok, will reoder the bind sequence too, thanx.
