net: sh_eth: Allocate bb_miiphy using bb_miiphy_alloc() and fill in callbacks

Browse Source 
Allocate bb_miiphy using bb_miiphy_alloc() and fill in callbacks
currently listed in bb_miiphy_buses[] array. This is a temporary
duplication of assignment to avoid breakage, which will be removed
in follow up patches. At this point, the bb_miiphy callbacks can
reach these accessors by doing container_of() on struct mii_dev.
