Subject: [PATCH net-next 5/9] net: dsa: Export suspend/resume functions

In preparation for allowing switch drivers to implement system-wide
suspend/resume functions, export dsa_switch_suspend and
dsa_switch_resume() such that these are callable from the appropriate
driver specific suspend/resume functions.
