[ARM] pxa/MioA701: improve power supply sources
Take advantage of the newly created wm97xx battery driver and remove useless code in mioa701 board code. Add also the ac connection detect capability after the matching gpio was discovered. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>
