Add the property enet-phy-pair-polarity to describe the polarity of the
PHY pairs. To ease PCB designs some manufacturers allow to wire the
pairs with a reverse polarity and provide a way to configure it.
The property 'enet-phy-pair-polarity' sets the polarity of each pair.
Bit 0 to 3 configure the polarity or pairs A to D, if set to 1 the
polarity is reversed for this pair.
