Merge branch 'net-dsa-b53-non-legacy'

Russell King says:

====================
net: dsa: b53: convert to phylink_generic_validate() and mark as non-legacy

This series converts b53 to use phylink_generic_validate() and also
marks this driver as non-legacy.

Patch 1 cleans up an if() condition to be more readable before we
proceed with the conversion.

Patch 2 populates the supported_interfaces and mac_capabilities members
of phylink_config.

Patch 3 drops the use of phylink_helper_basex_speed() which is now not
necessary.

Patch 4 switches the driver to use phylink_generic_validate()

Patch 5 marks the driver as non-legacy.
