Hmm, while these huge number of clocks are somewhat strange,
shouldn't it be named something with _rmii instead of _speed then?
Also, I don't see any clk_enable action for that new clock, so you could
end up with being off?
And someone could convert the driver to use the new clk-bulk APIs [0],
so the large number of clk_prepare_enable calls would be a bit
trimmed down.
