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.
