realtek: pcs: rtl93xx: implement restarting auto-negotiation

Browse source 
Add a new SerDes operation for restarting in-band negotiation including
an implemenation for RTL93xx, and call it from .pcs_an_restart.

This is a prerequisite for configuration of the in-band advertisement,
as changing it requires triggering a restart of auto-negotiation.
