Further fix for dsa unbinding

This serie fixes further issues for DSA dynamic unbinding. Frode Isaksen's patches make usage of delayed work and fixes kernel crashes when dsa is unbind.
The other patches are simple fixes to permit cleanup and avoid netdev related crashes.

Frode Isaksen (3):
net: dsa: Use delayed work instead of timer+work for polling
net: dsa: Do not reschedule polling if driver removed
net: phy: Stop 'phy-state-machine' and 'phy_change' work on remove

Neil Armstrong (3):
net: dsa: allow switch drivers to cleanup their resources
net: dsa: cleanup resources upon module removal
net: dsa: Add missing master netdev dev_put() calls
