[SRU][O][PATCH 3/3] drm/xe/display: Add missing HPD interrupt enabling during non-d3cold RPM resume

[Thibault Ferrante]

From: Imre Deak <imre.deak at intel.com>

BugLink: https://bugs.launchpad.net/bugs/2102378

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.
