net: sparx5: add support for tc flower redirect action
Add support for the flower redirect action. Two VCAP actions are encoded
in the rule - one for the port mask, and one for the port mask mode.
When the rule is hit, the port mask is used as the final destination
set, replacing all other port masks.
