Instead of registering the switch MDIO bus in the probe() function, move
the call to gswip_mdio() into the .setup() DSA switch op, so it can be
reused independently of the probe() function.

Instead of matching against the child node's compatible string also
support locating the node of the device tree node of the MDIO bus
in the standard way by referencing the node name ("mdio").

The MaxLinear GSW1xx family got a single (R)(G)MII port at index 5 but
the registers MII_PCDU and MII_CFG are those of port 0.
Allow applying an offset for the port index to access those registers.

We can safely ignore SerDes interface modes 1000Base-X, 2500Base-X and
SGMII in phylink_mac_config() as they are being taken care of by the PCS
and the SGMII port anyway doesn't have MII_CFG and MII_PCDU registers
and hence gswip_phylink_mac_config() is already a no-op apart from
outputing a misleading error message.
Return early in case of SerDes interface modes to avoid printing that
error message.

Call mac_select_pcs() function if provided in struct gswip_hwinfo.
The MaxLinear GSW1xx series got one port wired to a SerDes PCS and
PHY which can do 1000Base-X, 2500Base-X and SGMII. Support for the
SerDes port will be provided using phylink_pcs, so provide a
convenient way for mac_select_pcs() to differ based on the hardware
model.

Move the lantiq_gswip driver to its own folder and update
MAINTAINERS file accordingly.
This is done ahead of extending the driver to support the MaxLinear
GSW1xx series of standalone switch ICs, which includes adding a bunch
of files.
