[net-next,v5,0/9] net: lan966x: Add switchdev and vlan support

Message

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.

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
