The above mentioned function will also handle SGMII as well.

I noticed that you have phylink_decode_sgmii_work(), so I will try to
export it also.

Another approach would be to split phylink_mii_c22_pcs_decode_state()
so that the appropriate decode function is selected depending on the
interface state, which may be a better idea.
