drm/i915: add VGA hotplug support for 945+
Add VGA port hotplug detection to the i915 driver. When KMS is enabled,
plugging in or removing a VGA cable from the VGA connector will
generate a uevent, which indicates to userspace that it should re-probe
outputs on this device (to determine modes, etc.).
