[PATCH 1/3] ARM: dts: sun7i: Fix A20-OLinuXino-MICRO dts for use with LAN8710

[Stefan Mavrodiev]

>From revision J the board uses new phy chip LAN8710. Compared
with RTL8201, RA17 pin is TXERR. It has pullup which causes phy
not to work. To fix this, PA17 must be configured output-low.

This patch is compatible with earlier board revisions, since this
pin wasn't connected to phy.
