Subject: drm/amd/display: refine the EDID override
Git-commit: 575d0df6dae46f1b5d26a35ce0ccbc5aafd40e1d
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
[Why]
We already get the SBIOS EDID via ACPI on KMD,
but after that, we just use the monitor EDID to set it HDR caps
[How]
Make the SBIOS EDID override to read_edid()
That can change the read EDID caps from the right EDID
