[PATCH net-next] net: dsa: realtek: convert to phylink_generic_validate()

[Russell King (Oracle)]

Populate the supported interfaces and MAC capabilities for the Realtek
rtl8365 DSA switch and remove the old validate implementation to allow
DSA to use phylink_generic_validate() for this switch driver.

I seem to have missed this driver, so here's an update for it - but only
build tested.
