Subject: drm/i915: split the dpll clock compute out from display vtable.
Git-commit: 903f3806f3e83b6590a7ed6846fb206ec505457f
Patch-mainline: v5.16-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

this single function might be possible to merge later, but
for now it's simple to just split it out.
