Subject: [PATCH RFC net-next v2 04/10] net: dsa: mt7530: remove interface
checks
As phylink checks the interface mode against the supported_interfaces
bitmap, we no longer need to validate the interface mode, nor handle
PHY_INTERFACE_MODE_NA in the validation function. Remove these to
simplify the implementation.
