[PATCH v3 11/19] drm/i915: Move unload time display power domain uninit later

[Imre Deak <imre.deak@intel.com>]

Move the power domain uninitialization later so that it matches its
corresponding init order. Since we access the HW during the later
unitialization steps keep a wake reference until after the last such
step.
