Subject: [PATCH net 4/7] net: dsa: mt7530: set both CPU port interfaces to PHY_INTERFACE_MODE_NA

From: Arınç ÜNAL <arinc.unal@...nc9.com>

Set interfaces of both CPU ports to PHY_INTERFACE_MODE_NA. Either phylink
or mt7530_setup_port5() on mt7530_setup() will handle the rest.

This is already being done for port 6, do it for port 5 as well.

Fixes: 38f790a80560 ("net: dsa: mt7530: Add support for port 5")
