[PATCH RFC net-next v2 4/7] net: stmmac: add struct stmmac_pcs_info

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

We need to describe one more register (offset and field bitmask) to
the PCS code. Move the existing PCS offset and interrupt enable bits
to a new struct and pass that in to stmmac_integrated_pcs_init().
