drm/i915/irq: move locking inside vlv_display_irq_postinstall()
All users of vlv_display_irq_postinstall() outside of
intel_display_irq.c have a lock/unlock pair. Move the locking inside the
function. Add an unlocked variant for internal use, similar to the
_vlv_display_irq_reset() and vlv_display_irq_reset() functions.
