Subject: vgaarb: remove vga_conflicts

Git-commit: b0b514abc4cf2841ee1e0833252b2e8a78401276
Patch-mainline: v5.15-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
vga_conflicts only has a single caller and none of the arch overrides
mentioned in the comment. Just remove it and the thus dead check in the
caller.
