[SRU][O][PATCH v2 0/4] HDMI cause display malfunctioning on BMG hardware

[Thibault Ferrante]

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

[ Impact ]

 * There are 4 ports on the BMG (3 DP and 1 HDMI). Display for those 3 DP ports are working fine,
 including single and double monitor display. However, whenever the HDMI port is used, after that,
 the 3 DP ports will not be working. Meanwhile, the HDMI port is still working.

[ Fix ]

* Upstream fix:
 drm/xe: Remove runtime argument from display s/r functions
 drm/xe/display: Separate the d3cold and non-d3cold runtime PM handling
 drm/xe/display: Add missing HPD interrupt enabling during non-d3cold RPM resume
 drm/xe: Fix missing conversion to xe_display_pm_runtime_resume

[ Test Plan ]

 1. Plug in HDMI
 2. Plug out HDMI
 3. Plug in DP

This is already tested/verified on oracular:linux-intel which includes those fixes.

[ Where problems could occur ]

 * BMG specific regression

[ Other Info ]

 * Fix pointed out by intel engineer. Backport done by them, just checked/modified it to follow the SRU process.
