Vladimir Oltean 2e554a7a5d net: dsa: propagate switchdev vlan_filtering prepare phase to drivers 
A driver may refuse to enable VLAN filtering for any reason beyond what
the DSA framework cares about, such as:
- having tc-flower rules that rely on the switch being VLAN-aware
- the particular switch does not support VLAN, even if the driver does
  (the DSA framework just checks for the presence of the .port_vlan_add
  and .port_vlan_del pointers)
- simply not supporting this configuration to be toggled at runtime

Currently, when a driver rejects a configuration it cannot support, it
does this from the commit phase, which triggers various warnings in
switchdev.

So propagate the prepare phase to drivers, to give them the ability to
refuse invalid configurations cleanly and avoid the warnings.

Since we need to modify all function prototypes and check for the
prepare phase from within the drivers, take that opportunity and move
the existing driver restrictions within the prepare phase where that is
possible and easy.

/* Port Group IDs (PGID) are masks of destination ports.
*
* For L2 forwarding, the switch performs 3 lookups in the PGID table for each
* frame, and forwards the frame to the ports that are present in the logical
* AND of all 3 PGIDs.
*
* These PGID lookups are:
* - In one of PGID[0-63]: for the destination masks. There are 2 paths by
* which the switch selects a destination PGID:
* - The {DMAC, VID} is present in the MAC table. In that case, the
* destination PGID is given by the DEST_IDX field of the MAC table entry
* that matched.
* - The {DMAC, VID} is not present in the MAC table (it is unknown). The
* frame is disseminated as being either unicast, multicast or broadcast,
* and according to that, the destination PGID is chosen as being the
* value contained by ANA_FLOODING_FLD_UNICAST,
* ANA_FLOODING_FLD_MULTICAST or ANA_FLOODING_FLD_BROADCAST.
* The destination PGID can be an unicast set: the first PGIDs, 0 to
* ocelot->num_phys_ports - 1, or a multicast set: the PGIDs from
* ocelot->num_phys_ports to 63. By convention, a unicast PGID corresponds to
* a physical port and has a single bit set in the destination ports mask:
* that corresponding to the port number itself. In contrast, a multicast
* PGID will have potentially more than one single bit set in the destination
* ports mask.
* - In one of PGID[64-79]: for the aggregation mask. The switch classifier
* dissects each frame and generates a 4-bit Link Aggregation Code which is
* used for this second PGID table lookup. The goal of link aggregation is to
* hash multiple flows within the same LAG on to different destination ports.
* The first lookup will result in a PGID with all the LAG members present in
* the destination ports mask, and the second lookup, by Link Aggregation
* Code, will ensure that each flow gets forwarded only to a single port out
* of that mask (there are no duplicates).
* - In one of PGID[80-90]: for the source mask. The third time, the PGID table
* is indexed with the ingress port (plus 80). These PGIDs answer the
* question "is port i allowed to forward traffic to port j?" If yes, then
* BIT(j) of PGID 80+i will be found set. The third PGID lookup can be used
* to enforce the L2 forwarding matrix imposed by e.g. a Linux bridge.
*/
/* Reserve some destination PGIDs at the end of the range:
* PGID_CPU: used for whitelisting certain MAC addresses, such as the addresses
* of the switch port net devices, towards the CPU port module.
* PGID_UC: the flooding destinations for unknown unicast traffic.
* PGID_MC: the flooding destinations for broadcast and non-IP multicast
* traffic.
* PGID_MCIPV4: the flooding destinations for IPv4 multicast traffic.
* PGID_MCIPV6: the flooding destinations for IPv6 multicast traffic.
