Subject: drm/amd/display: Pass PCI deviceid into DC
Git-commit: d942856865c733ff60450de9691af796ad71d7bc
Patch-mainline: v5.15-rc4
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]
pci deviceid not passed to dal dc, without proper break,
dcn2.x falls into dcn3.x code path

[how]
pass in pci deviceid, and break once dal_version initialized.
