drm/i915: Move audio deinit after disabling polling

Browse Source 
Deinitialize audio during driver unload after disabling polling. This is
in preparation to do all the display HW init/deinit steps at a point
where no HPD IRQ or polling initiated connector detection or modeset can
change the HW state. This may still happen here via an HPD IRQ ->
hotplug detection work or a connector sysfs (state/detect) access, but
these will be prevented by later changes in this patchset.
