PATCH 1/1 beagle_x15: increase phy autoneg timeout

When Beagle X15 is connected to Gigabit switch, it takes more time to finish auto-negotiation than on a 10/100 switch.

The default 4 second limit times-out more often than not. This is observed when testing with a D-Link DGS-1008A desktop switch.

Increase the auto-negotiation time-out for Beagle-X15 to handle this case.
