[PATCH v2 05/10] net: dsa: felix: configure the in-band autoneg property based on OF node info

Instead of trying to guess which operating modes need in-band
negotiation to be active and which ones don't, parse the available
information from the device tree. That will be correct in the cases we
can already guess, and more.
