The GPIO polarity passed to phy-reset-gpio is ignored by the FEC
driver and it is assumed to be active low.
It can be active high only when the 'phy-reset-active-high' property
is present.
The current examples pass active high polarity and work fine, but
in order to improve the documentation make it explicit what the real
polarity is.
