[PATCH 3/3] ARM: dts: sun7i: Add uart4 support for BananaPro, disable uart2

[Hans de Goede]

From: Michael Ring <mail at michael-ring.org>

The BananaPro uses uart4 for the default rx/tx pins on the 40 pins connector,
so enable uart4.

Uart2 is also available at the bananapro io-pins, but like on the bananapi
the primary function of the pins is to act as gpios, see:
http://forum.lemaker.org/forum.php?mod=viewthread&tid=10852

Disable the uart2 node by default, but leave it in place so that people
can easily enable it.
