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.

I'll see if I can cherry-pick this into Trusty and build a test kernel.
