Despite being documented as self-clearing, the RANEG bit sometimes
remains set, preventing auto-negotiation from happening.
Manually clear the RANEG bit after 10ms as advised by MaxLinear.
In order to not hold RTNL during the 10ms of waiting schedule
delayed work to take care of clearing the bit asynchronously, which
is similar to the self-clearing behavior.
