Add a hwmod entry for the davinci_mdio hardware block. This aliases the
cpsw_125mhz_clkdm and re-uses am33xx_cpgmac0_hwmod_class.

I'm still not totally confident with the hwmod environment, so I'm not
entirely sure whether sharing the hwmod_class is the right thing to do
here. However, I can at least get ethernet to work on my board now.
