ath79: allow to override AR8033 SGMII aneg status
In order to make the QCA955x SGMII workaround work, the unsuccessful SGMII autonegotiation on the AR8033 should not block the PHY state-machine. Otherwise, the ag71xx driver never becomes aware of the copper-side link-establishment and the workaround is never executed.
