generic: ar8216: start AR8327 switch from the probe routine

The AR8327 switch gets its configuration from platform
data or from the device-tree. This allows to start it
from the probe routine. Doing so makes it usable with
ethernet drivers which only connects to the PHY device
when the ethernet interface is opened.
