Subject: [PATCH] fec: Revert "fec: Do not assume that PHY reset is active low"

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

In order to keep DT compatibility we need to revert this, otherwise the original
dts files will no longer work with this driver change.

This reverts commit 7a399e3a2e05bc580a78ea72371b3896827f72e1.

David,

We need this for 3.13.

Sorry for the breakage.
