net: tulip: Rename PCI driver struct to end in _driver

This is not only a cosmetic change because the section mismatch checks
also depend on the name and for drivers the checks are stricter than for
ops.

However xircom_driver also passes the stricter checks just fine, so no
further changes needed.
