The current dsa_register_switch function takes a useless struct device
pointer argument, which always equals ds->dev.
Drivers either call it with ds->dev, or with the same device pointer
passed to dsa_switch_alloc, which ends up being assigned to ds->dev.
This patch removes the second argument of the dsa_register_switch and
_dsa_register_switch functions.

Now that the DSA public header includes switchdev.h, use the provided
switchdev_obj_dump_cb_t typedef for the object dump callback.

DSA drivers and core use switchdev. Include switchdev.h only once, in
the dsa.h public header, so that inclusion in DSA drivers or forward
declarations of switchdev structures in not necessary anymore.

A dsa_switch_tree instance holds a dsa_switch pointer and a port index
to identify the switch port to which the CPU is attached.
Now that the DSA layer has a dsa_port structure to hold this data, use
it to point the switch CPU port.
This patch simply substitutes s/dst->cpu_switch/dst->cpu_dp->ds/ and
s/dst->cpu_port/dst->cpu_dp->index/.

Now that DSA exposes the bridge device pointer to which a port belongs,
use it when programming the port based VLANs and thus remove the cache.

Upon reception of the NETDEV_CHANGEUPPER, a leaving port is already
unbridged, so reflect this by assigning the port's bridge_dev pointer to
NULL before calling the port_bridge_leave DSA driver operation.
Now that the bridge_dev pointer is exposed to the drivers, reflecting
the current state of the DSA switch fabric is necessary for the drivers
to adjust their port based VLANs correctly.
Pass the bridge device pointer to the port_bridge_leave operation so
that drivers have all information to re-program their chips properly,
and do not need to cache it anymore.

Change the ports[DSA_MAX_PORTS] array of the dsa_switch structure for a
zero-length array, allocated at the same time as the dsa_switch
structure itself. A dsa_switch_alloc() helper is provided for that.
This commit brings no functional change yet since we pass DSA_MAX_PORTS
as the number of ports for the moment. Future patches can update the DSA
drivers separately to support dynamic number of ports.

In preparation for allowing dsa_register_switch() to be supplied with
device/platform data, pass down a struct device pointer instead of a
struct device_node.

This patch contains initial support for the QCA8337 switch. It
will detect a QCA8337 switch, if present and declared in the DT.
Each port will be represented through a standalone net_device interface,
as for other DSA switches. CPU can communicate with any of the ports by
setting an IP@ on ethN interface. Most of the extra callbacks of the DSA
subsystem are already supported, such as bridge offloading, stp, fdb.
