Merge branch 'phy-improve-stopping-PHY'

Heiner Kallweit says:

====================
net: phy: improve stopping PHY

This patchset improves and simplifies stopping the PHY.

Heiner Kallweit (3):
  net: phy: stop PHY if needed when entering phy_disconnect
  net: phy: ensure phylib state machine is stopped after calling phy_stop
  net: phy: remove phy_stop_interrupts

v2:
- break down the patch to a patchset
v3:
- don't warn if driver didn't call phy_stop before phy_disconnect
