MFD: ucb1x00-core: add wakeup support
Add genirq wakeup support for the ucb1x00 device. This allows an attached gpio_keys driver to wakeup the system. Touchscreen is also possible. When there are no wakeup sources, ask the platform to assert the reset signal to avoid any unexpected behaviour; this also puts the reset signal at the right level when power is removed from the device.
