Subject: [PATCH v5 2/3] ARM: dts: twl4030: Add missing madc reference for bci subnode

From: Marek Belisko <marek@...delico.com>

The twl4030_charger driver expects an iio channel to detect the
presence of an AC charger by looking at VAC (madc channel 11).
This definition is missing in the device tree.
