[ARM] pxa/MioA701: discovered new gpio definitions.
The charger enable gpio is straight (1 means draw from USB Vbus, 0 mean do not draw). The USB Vbus sensing is inverted (1 means no Vbus voltage sensed, 0 means Vbus voltage present). Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>
