mb/siemens/mc_ehl2: Enable Marvell PHY 88E1512 driver 

This mainboard has three Marvel PHYs connected to the internal SOC GbE
controllers. The default LED status after HW reset of this PHYs shows a
different mode than what is needed. LED[2] is not connected on this
mainboard.

This patch sets the following LED status:
LED[0] - 7 = On - 1000 Mbps Link, Off - Else
LED[1] - 1 = On - Link, Blink - Activity, Off - No Link
LED[2] - not connected

TEST=Try different register values to verify LED feature.
