Russell King says:

====================
Convert mvpp2 to phylink supported_interfaces

This patch series converts mvpp2 to use phylinks supported_interfaces
bitmap to simplify the validate() implementation. The patches:

1) Add the supported interface modes the supported_interfaces bitmap.
2) Removes the checks for the interface type being supported from
   the validate callback
3) Removes the now unnecessary checks and call to
   phylink_helper_basex_speed() to support switching between
   1000base-X and 2500base-X for SFPs
4) Cleans up the resulting validate() code.

(3) becomes possible because when asking the MAC for its complete
support, we walk all supported interfaces which will include 1000base-X
and 2500base-X only if the comphy is present.
