net: mvpp2: fix validate for PPv2.1

The Phylink validate function is the Marvell PPv2 driver makes a check on the GoP id. This is valid an has to be done when using PPv2.2 engines but makes no sense when using PPv2.1. The check done when using an RGMII interface makes sure the GoP id is not 0, but this breaks PPv2.1. Fixes it.
