====================
net: dsa: rzn1-a5psw: add support for vlan and .port_bridge_flags

this series enables vlan support in Renesas RZN1 internal ethernet switch,
and is a follow up to the work initiated by Clement Leger a few months ago,
who handed me over the topic.
This new revision aims to iron the last few points raised by Vladimir to
ensure that the driver is in line with switch drivers expectations, and is
based on the lengthy discussion in [1] (thanks Vladimir for the valuable
explanations)

RESEND V4:
 - Resent due to net-next being closed

V4:
 - Fix missing CPU port bit in a5psw->bridged_ports
