From: Maxim Kochetkov <fido_...@inbox.ru>
Add the register definitions for the MSCC MIIM MDIO controller in
preparation for seville_vsc9959.c to create its accessors for the
internal MDIO bus.
Since we've introduced elements to ocelot_regfields that are not
instantiated by felix and ocelot, we need to define the size of the
regfields arrays explicitly, otherwise ocelot_regfields_init, which
iterates up to REGFIELD_MAX, will fault on the undefined regfield
entries (if we're lucky).
