This patch series extends lan966x with switchdev and vlan support.
The first patches just adds new registers and extend the MAC table to
handle the interrupts when a new address is learn/forget.

v6->v7:
- fix build issues when compiling as a module

v5->v6:
- fix issues with the singletones, they were not really singletons
- simplify the case where lan966x ports are added to bridges with foreign
ports
- drop the cases NETDEV_PRE_UP and NETDEV_DOWN
- fix the change of MAC address
- drop the callbacks .ndo_set_features, .ndo_vlan_rx_add_vid,
.ndo_vlan_rx_kill_vid
- remove duplicate code when port was added in a vlan, the MAC entries
will be added by the fdb

v4->v5:
- make the notifier_block from lan966x to be singletones
- use switchdev_handle_port_obj_add and switchdev_handle_fdb_event_to_device
when getting callbacks in the lan966x
- merge the two vlan patches in a single one

v3->v4:
- split the last patch in multiple patches
- replace spin_lock_irqsave/restore with spin_lock/spin_unlock
- remove lan966x_port_change_rx_flags because it was copying all the frames to
the CPU instead of removing all RX filters.
- implement SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS
- remove calls to __dev_mc_unsync/sync as they are not needed
- replace 0/1 with false/true
- make sure that the lan966x ports are not added to bridges that have other
interfaces except lan966x
- and allow the lan966x ports to be part of only the same bridge.

v2->v3:
- separate the PVID used when the port is in host mode or vlan unaware
- fix issue when the port was leaving the bridge

v1->v2:
- when allocating entries for the mac table use kzalloc instead of
devm_kzalloc
- also use GFP_KERNEL instead of GFP_ATOMIC, because is never called
in atomic context
- when deleting an mac table entry, the order of operations was wrong
- if ana irq is enabled make sure it gets disabled when the driver is
removed
