[PATCH] ppc32: board-specific part of fs_enet update

This contains board-specific portion to respect driver changes (for 8272ads ,
885ads and 866ads).  Altered platform_data structures as well as initial setup
routines relevant to fs_enet.

Changes to the mpc8560ads ppc/ code are also introduced, but mainly as
reference, since the entire board support is going to appear in arch/powerpc.
