c378d5e953 generic: ar8216: add AR8337N switch support
This patch is needed to use the switch inside the Sitecom WLR-8100;
it was unusable and detected as Generic-Phy before.

since ar8337 is behaving like ar8327
generally do the same thing

72253b9073 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.

d64888ffc0 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.
