net: dsa: realtek: remove realtek,rtl8367s string

There is no need to add new compatible strings for each new supported
chip version. The compatible string is used only to select the subdriver
(rtl8365mb.c or rtl8366rb.c). Once in the subdriver, it will detect the
chip model by itself, ignoring which compatible string was used.
