drm/xe/pf: Expose PF service details via debugfs
Browse files Browse the repository at this point in the history
For debug purposes we might want to verify which registers values
PF is sharing with VFs and to view which VF/PF ABI versions were
negotiated by the VFs. Plug the 'print' functions already provided
by the PF service code into our debugfs.
