i40e: Implement configfs for NPAR BW configuration
Add configfs controls to get, set and commit NPAR BW configurations.
We export three controls:
min_bw - Can take a value from 0 to 100 inclusive
max_bw - Can take a value from 1 to 100 inclusive
commit - A write-only control that accepts only a value of 1 and will
cause the BW settings to be permanently committed to NVM so
that they are persistent across power cycles and system
resets
The BW values are relative and are expressed as percentages. For more
information on the interpretation of the BW settings see the Dell
specifications for NPAR.
Also update the copyright year.
