DRM/i915: Remove i965_hpd_irq_setup.
After "Convert HPD interrupts to make use of HPD pin assignment in encoders." This function is now basically the same as i915_hpd_irq_setup(). Consolidating both functions in one requires one more check for I915_HAS_HOTPLUG(dev) in the i965 code path and one more check for IS_G4X(dev) in the i915 code path. These are considered harmless.
