drm/i915: don't touch the VDD when disabling the panel
I don't see a reason to touch VDD when we're disabling the panel:
since the panel is enabled, we don't need VDD. This saves a few sleep
calls from the vdd_on and vdd_off functions at every modeset.

[danvet: Fix the patch mangle wiggle has done ... Spotted by Paulo.
Also drop the runtime_pm_put call which now has to go due to different
patch ordering. Also from Paul.]
