The CPU port of realtek switches needs some proper PVID set to handle
untagged packets. Because the ethernet driver does no special VLAN
handling (see CPU tag RVID/RVID_SEL) as of now we can only steer
untagged packets by setting PVID for the CPU port. VLAN handling has
never been perfect but 3 events made things worse.
- Commit a376508216 ("rtl83xx: dsa: Do nothing when vid 0")
- Commit e691e2b302 ("rtl83xx: dsa: reset PVID to 1 instead of 0")
- Upgrade to kernel 6.6
Reasons are:
- Rejecting VID 0 disabled Linux initialization routines
- Initialization for PVID forgot to set priv->ports[port].pvid
- Kernel 6.6 does no longer clarify CPU port as untagged
To fix this prepare the VID 0 setup inside the driver. Join all ports
to VID 0 and let no one from outsinde interfere with this setup.
Especially ignore PVID settings for the CPU port for all further
VLAN commands.

Since kernel commit c5714f68a76bcad3d ("net: phylink: explicitly invalidate
link_state members in mac_config") it should be clear that link data can
only be used in mac_link_up(). Refactor that for the RTL83xx targets.

Some devices (e.g. HP JG924A) hand over other than expected kernel boot
arguments. Looking at these one can see:
fw_init_cmdline: fw_arg0=00020000
fw_init_cmdline: fw_arg1=00060000
fw_init_cmdline: fw_arg2=fffdffff
fw_init_cmdline: fw_arg3=0000416c
Especially fw_arg2 should be the pointer to the environment and it looks
very suspicous. It is not aligned and the address is outside KSEG0 and
KSEG1. Booting the device will result in a hang. Do better at verifying
the address.

The DSA framework has changed a bit since 6.1, lets adapt to match.
Currently there is no one-patch-fits-all solution to directly fix
all errors up to 6.6. So cover the final differences with this
second patch.
Most notable upstream changes are:
- a88dd7538461 ("net: dsa: remove legacy_pre_march2020 detection")

The DSA framework has changed a bit since 5.15, lets adapt to match.
Currently there is no one-patch-fits-all solution to directly fix
all errors up to 6.6. So at least take all the already known changes
that cover differences between 5.15 and 6.1
Most notable upstream changes are:
- d3eed0e57d5d ("net: dsa: keep the bridge_dev and bridge_num as part
of the same structure")
Update of port_bridge_{join,leave}: use same helper as upstream
- c26933639b54 ("net: dsa: request drivers to perform FDB isolation")

This is not a surprise. Before upgrade to 6.6 we refactored the mdio part of
the ethernet driver and knew that changes will come. Drop all unnecessary
stuff from the old world and adapt to the new kernel.
- remove legacy functions
- directly link new functions
- adapt to new shared base address
- remove references to old MDIO bus capabilities

With the new kernel the MDIO bus gets created after the smbus
read/write functions are used. Make use of native functions.
Relocate bus initialization into a separate function to make
patch easier to read.

With this patch all platform specific changes for kernel 6.6 are in place.
Realtek devices are bootable from serial console. VPE is fully functional
on devices that support it. The switch functions (ethernet and DSA) are
not enabled yet.
Boot tested on RTL8380 (Linksys LGS310C) and RTL8393 (Zyxel GS1920-24).
