[PATCH v3 4/4] net/txgbe: add VF support for Amber-Lite 40G NIC

[Zaiyu Wang <zaiyuwang@trustnetic.com>]

VF support for the 40G NIC was previously omitted; only the 25G VF was
added. Now add 40G VF support based on the existing 25G VF implementation,
with no major changes but only device ID adaptation.

Also, drop the redundant mac type check in txgbe_check_mac_link_vf(),
as the function now handles all VF types uniformly.
