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.

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 ar8216_mib_{capture,flush} functions are similar.
Move the common code into a helper and use that from
the original functions.
This change also fixes a lockdep warning in
ar8216_mib_flush.
