Merge branch 'net-dsa-realtek-rtl8366rb-use-generic-rtl83xx-code'

Linus Walleij says:

====================
net: dsa: realtek: rtl8366rb: Use generic RTL83xx code

As a follow-up to Luiz's and Alvin's series improvining the
generic handling of the Realtek DSA switches, this small
series brings the RTL8366RB closer to the way things are done
in the RTL8365MB driver.

This patch series switches over to using the generic helpers
for:

- Bridge joining and leaving (isolation)
- STP handling
- Learning enable/disable

It would be appreciated if this doesn't lead to AI-automated
request to fix the entire universe (hi Sashiko, I'm looking
at you but I bet you will do you compulsive C3P0-style review
anyway) since I'm just moving code around so some helper
functions come before their new users. The code itself is
pretty straight-forward.
