[PATCH v2 4/4] drm/xe/display: Add missing HPD interrupt enabling during non-d3cold RPM resume

[Imre Deak <imre.deak@intel.com>]

Atm the display HPD interrupts that got disabled during runtime
suspend, are re-enabled only if d3cold is enabled. Fix things by
also re-enabling the interrupts if d3cold is disabled.
