net: phylink: pass phylink and pcs into phylink_pcs_neg_mode()

Browse Source 
Move the call to phylink_pcs_neg_mode() in phylink_major_config() after
we have selected the appropriate PCS to allow the PCS to be passed in.

Add struct phylink and struct phylink_pcs pointers to
phylink_pcs_neg_mode() and pass in the appropriate structures. Set
pl->pcs_neg_mode before returning, and remove the return value.

This will allow the capabilities of the PCS and any PHY to be used when
deciding which pcs_neg_mode should be used.
