====================
net: phy: improve and simplify phylib state machine

This patch series is based on two axioms:

- During autoneg a PHY always reports the link being down

- Info in clause 22/45 registers doesn't allow to differentiate between
  these two states:
  1. Link is physically down
  2. A link partner is connected and PHY is autonegotiating
  In both cases "link up" and "aneg finished" bits aren't set.
  One consequence is that having separate states PHY_NOLINK and PHY_AN
  isn't needed.

By using these two axioms the state machine can be significantly
simplified.
