net: mvpp2: Read phy-speed from DT to select between 1GB and 2.5GB SGMII
Read the "phy-speed" DT property to differentiate between 1 and 2.5GB
SGMII operations. Please note that its unclear right now, if this
DT property will be accepted in mainline Linux. If not, we need to
revisit this code and change it to use the accepted property.
