Gabor Juhos 562eca38dc 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.

Gabor Juhos e4468b8202 generic: ar8216: register the switch from the probe routine
Currently the switch gets registered when an ethernet
driver connects to a PHY of the switch. This method does
not work with the ethernet drivers which are connecting
to the PHY from their ndo_open callback. With those
ethernet drivers, the driver tries to register the switch
each time when the etherned device is opened and this causes
a deadlock.

Move the switch registration into the probe routine to fix
this problem.

The current code uses the 'remove' callback to disable
packet mangle on the underlying ethernet device.
However the attached_dev is always NULL when the
'remove' callback is called by phylib, and this causes
NULL pointer dereference, like this:
