[PATCH net-next v2 1/7] net: ethernet: oa_tc6: Forward declare struct mii_bus

[Iustin Stolniceanu]

The Clause 45 MDIO accessors in oa_tc6.h take a struct mii_bus pointer,
but the header does not declare the type. A file that includes oa_tc6.h
before linux/phy.h or linux/mdio.h gets a "'struct mii_bus' declared
inside parameter list" warning, which is an error with CONFIG_WERROR.

lan865x and adin1140 are not affected, as they include one of those
first. The adin1110 driver, which gets OA TC6 support later in this
series, does not, and hits the warning.
