net: dsa: realtek: use the same mii bus driver for both interfaces

The realtek-mdio will now use this driver instead of the generic DSA
driver ("dsa user smi"), which should not be used with OF[1].

With a single ds_ops for both interfaces, the ds_ops in realtek_priv is
no longer necessary. Now, the realtek_variant.ds_ops can be used
directly.

The realtek_priv.setup_interface() has been removed as we can directly
call the new common function.
