[PATCH net] net: dsa: realtek: don't parse compatible string for RTL8366S

[Alvin Šipraga]

From: Alvin Šipraga <alsi@bang-olufsen.dk>

This switch is not even supported, but if someone were to actually put
this compatible string "realtek,rtl8366s" in their device tree, they
would be greeted with a kernel panic because the probe function would
dereference NULL. So let's just remove it.
