[PATCH 6/9] fs_enet: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING is set.

Hi Scott,

I apologize for bringing this after so much time. Hope the "better late than 
never" motto applies.

We're loosing the possibility of having MDC and MDIO on different ports. This 
is quite easy to fix for the non-CONFIG_PPC_CPM_NEW_BINDING case but I'm not 
familiar with OF bindings (yet) to fix the CONFIG_PPC_CPM_NEW_BINDING case.
