Subject: drm/edid: convert version_greater() to drm_edid
Git-commit: d0edd3c1a7e859a5899c26e2906e80f4ac798fa9
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

We'll need to propagate drm_edid everywhere. Also make version_greater()
a function for type safety.
