Bjorn Andersson fa0048a4b1 drm/msm/dp: Free resources after unregistering them 
The DP component's unbind operation walks through the submodules to
unregister and clean things up. But if the unbind happens because the DP
controller itself is being removed, all the memory for those submodules
has just been freed.

Change the order of these operations to avoid the many use-after-free
that otherwise happens in this code path.

Fixes: c943b4948b58 ("drm/msm/dp: add displayPort driver support")
