[PATCH 2/3] ARM: dts: sun7i: Add uart2 support for BananaPi

[Hans de Goede <hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

From: Michael Ring <mail-u1jPNj63thkWnkcawLe0jA@public.gmane.org>

Uart2 is available at the bananapi io-pins, add a dts node for this
(so that people can easily enable it) but leave it disabled as the pins
are primarily intended for gpio as documented here:
