i40e: Removal of code which relies on BASE VEB SEID

Orabug: 22342532

Fixed mapping of SEID is removed from specification. Hence
this patch removes code which was using hard coded base VEB SEID.

Changed FCoE code to use "hw->pf_id" to obtain correct "idx"
and verified.

Removed defines for BASE VSI/VEB SEID and BASE_PF_SEID since it
is not used anymore.
