From: Vladimir Oltean <vladimir.oltean@nxp.com>

Russell points out that there is no user of phylink_pcs_neg_mode()
outside of phylink.c, nor is there planned to be any, so we can just
move it there.

Hi,

You don't need this patch for your series, and you're bypassing my
ability to decide when this patch should be merged (which is not yet,
I want things to remain as-is for another cycle.)

In theory, looking at past history, 6.7 will probably be a LTS kernel,
but until that is known for certain, I don't want to commit to moving
this function in case LTS gets delayed by a cycle.

Please drop it from your series.

Thanks.
