From: Fabio Estevam <fabio.estevam@freescale.com>

Since commit 7a399e3a2e (fec: Do not assume that PHY reset is active low), we no
longer assume that the PHY reset is active low.

Now we need to retrieve this information from the device tree instead, so update
the binding documentation to make it clearer.
