bnxt_en: Add Virtual Admin Link State Support for VFs

The firmware can now cache the virtual link admin state (auto/on/off) of
all VFs and as such, the PF driver no longer has to intercept the VF
driver's port_phy_qcfg() call and then provide the link admin state.

If the FW does not have this capability, fall back to the existing
interception method.

The initial default link admin state (auto) is also set initially when
the VFs are created.
