driver inclusion
category: feature
bugzilla: NA
CVE: NA

--------------------------------

Uburma query vf related attributes, then store in cdev.
These attributes includes:
- congestion_ctrl_alg
- comp_vector_cnt
- utp_cnt
- port_count
- vf_cnt
- virtualization

All these attributes will be obtained by ubcore_query_device_status().
