ARM: pxa: hx4700: Enable ASIC3 GPIO as a wakeup source
This patch enables the ASIC3 GPIO (12) as a wakeup source:
1. Set the WAKEUP_ON_EDGE_RISE MFP config bits for GPIO12 in
hx4700_pin_config[].
2. Call gpio_set_wake() for GPIO12.
With GPIO12 thus enabled, the mfd/asic3 driver can enable its own GPIOs
as wakeup sources by implementing a irq_set_wake() handler.
