drm/xe/pf: Expose SR-IOV VFs configuration over debugfs

Browse source

We already have functions to configure VF resources and to print
actual provisioning details. Expose this functionality in debugfs
to allow experiment with different settings or inspect details in
case of unexpected issues with the provisioning.

As debugfs attributes are per-VF, we use parent d_inode->i_private
to store VFID, similarly how we did for per-GT attributes.
