06b9cce426 net: dsa: pass extack to .port_bridge_join driver methods
As FDB isolation cannot be enforced between VLAN-aware bridges in lack
of hardware assistance like extra FID bits, it seems plausible that many
DSA switches cannot do it. Therefore, they need to reject configurations
with multiple VLAN-aware bridges from the two code paths that can
transition towards that state:

- joining a VLAN-aware bridge
- toggling VLAN awareness on an existing bridge

The .port_vlan_filtering method already propagates the netlink extack to
the driver, let's propagate it from .port_bridge_join too, to make sure
that the driver can use the same function for both.

aac9400106 net: dsa: realtek: add new mdio interface for drivers
This driver is a mdio_driver instead of a platform driver (like
realtek-smi).

ds_ops was duplicated for smi and mdio usage as mdio interfaces uses
phy_{read,write} in ds_ops and the presence of phy_read is incompatible
with external slave_mii_bus allocation.

765c39a4fa net: dsa: realtek: convert subdrivers into modules
Preparing for multiple interfaces support, the drivers
must be independent of realtek-smi.

cd645dc556 net: dsa: realtek: remove direct calls to realtek-smi
Remove the only two direct calls from subdrivers to realtek-smi.
Now they are called from realtek_priv. Subdrivers can now be
linked independently from realtek-smi.

f5f119077b net: dsa: realtek: rename realtek_smi to realtek_priv
In preparation to adding other interfaces, the private data structure
was renamed to priv. Also, realtek_smi_variant and realtek_smi_ops
were renamed to realtek_variant and realtek_ops as those structs are
not SMI specific.
