net: dsa: realtek: rtl8365mb: add RTL8367S support

Browse Source 
Realtek's RTL8367S, a 5+2 port 10/100/1000M Ethernet switch.
It shares the same driver family (RTL8367C) with other models
as the RTL8365MB-VC. Its compatible string is "realtek,rtl8367s".

It was tested only with MDIO interface (realtek-mdio), although it might
work out-of-the-box with SMI interface (using realtek-smi).

This patch was based on an unpublished patch from Alvin Šipraga
<alsi@bang-olufsen.dk>.
