Introduce mdio_init() split off from mdio_alloc(), which is used

Replying here for the whole patch series...
I like where we get to at the end of this series, but I don't like the
intermediate state where the bb_miiphy_buses arrays still exist but are
unused. I also think we should introduce a new ops struct so we're not
duplicating function pointers in each instance of struct bb_miiphy_bus.
I would prefer the following order of changes, let me know if you think
this would be cleaner:
1) Introduce mdio_init().
2) Add mii member to struct bb_miiphy_bus.
3) Modify each driver to use the mii member of the appropriate struct
bb_miiphy_bus instance, calling mdio_init() instead of mdio_alloc().
At this point we're still using the instances in the statically
allocated bb_miiphy_buses array.
Those instances might be rodata , so using them as read-write storage
does not necessarily work , does it ?
None of the instances in the current U-Boot code are marked as const,
and the name field is already modified at runtime by each driver. So I
don't think we need to worry about them being rodata.
Can the compiler not decide to place the structure into rodata if it is
never written ?
