phylib: two dynamic mii_bus allocation fallout fixes
1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be
converted over to mdiobus_{alloc,free}().
2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its
struct fixed_mdio_bus and then use container_of() to go from the
former to the latter. Since mii bus structures are no longer
embedded, we need to do something like use the mii bus private
pointer to go from mii_bus to fixed_mdio_bus instead.
