ath79: allow to override AR8033 SGMII aneg status

Browse Source 
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.
