Hello Andy

I have never seen this kind of warnings. I prefer to not include the
stmmac.h in enh_desc.c and norm_desc.c but eventually to move the
following from stmmac.h to common.h:
   extern const struct stmmac_desc_ops enh_desc_ops;
   extern const struct stmmac_desc_ops ndesc_ops;
what do you think?
