drm/xe/pf: Promote PF debugfs function to its own file

Browse Source 
In upcoming patches, we will build on the PF separate debugfs
tree for all SR-IOV related files and this new code will need
dedicated file. To minimize large diffs later, move existing
function now as-is, so any future modifications will be done
directly in target file.
