net: fs_enet: Remove stale prototypes from fsl_soc.c

Commit 3dd82a1ea724 ("[POWERPC] CPM: Always use new binding.")
removed last use of init_fec_ioports() and init_fcc_ioports().

Remove stale prototypes then don't include anymore fs_enet_pd.h
which was only included to provide fs_platform_info structure
for the prototypes.
