net: phy: allow driver to implement their own aneg_done

Browse source 
Some PHYs out there can be very quirky with respect to how they would
report the auto-negotiation is completed. Allow drivers to override the
generic aneg_done() implementation by providing their own.

Since not all drivers have been updated yet to use genphy_aneg_done() as
aneg_done() callback, we explicitely check that this callback is valid
before calling into it.
