net: dsa: Encapsulate legacy switch drivers into dsa_switch_driver
In preparation for making struct dsa_switch_ops const, encapsulate it
within a dsa_switch_driver which has a list pointer and a pointer to
dsa_switch_ops. This allows us to take the list_head pointer out of
dsa_switch_ops, which is written to by {un,}register_switch_driver.
