net: ag71xx: remove interface checks in ag71xx_mac_validate()

Browse Source 
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.
