Subject: drm/amd/display: Loop through all pipes for DET allocation
Git-commit: 660f46e16c4b8a34978012a9f10a32a16db3e98f
Patch-mainline: v6.0-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 jsc#PED-2849
[Why & How]
There are cases where the pipes populated are not all at the top
of the pipes list under context. Loop through all pipes for DET
allocation instead of just the number of populated ones, even if
some unpopulated pipes are iterated through unnecessarily.
