net: enetc: add CBDR setup/teardown hooks to enetc_si_ops for VF support

The upcoming ENETC v4 VF will share the enetc-vf driver with the
existing v1 VF. However, ENETC v4 uses a revised CBDR (command BD ring)
setup/teardown API that differs from v1.

To support both versions in the same driver, add setup_cbdr() and
teardown_cbdr() function pointers to struct enetc_si_ops. This allows
each hardware version to register its own CBDR implementation:

- ENETC v1 VF registers enetc_setup_cbdr/enetc_teardown_cbdr (existing)
- ENETC v4 VF will register enetc4_setup_cbdr/enetc4_teardown_cbdr

Update the enetc-vf driver to call CBDR operations through si->ops
instead of directly invoking the v1 functions. This enables runtime
selection of the correct CBDR backend based on hardware version.

Changes:
- Add setup_cbdr() and teardown_cbdr() hooks to struct enetc_si_ops
- Register v1 CBDR functions in enetc_vsi_ops
- Replace direct calls with si->ops->setup_cbdr() and
  si->ops->teardown_cbdr() in enetc_vf.c

No functional changes to existing v1 VF behavior.
