dt-bindings: fec: Make the phy-reset-gpio polarity explicit

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.
