Input: wm97xx-core - support use as a wakeup source
The WM97xx touch screen controllers can be used to generate a wakeup event when the system is suspended. Provide a new core API call wm97xx_set_suspend_mode() allowing machine drivers to enable this. If no suspend_mode is provided then the touch panel will be powered down when the system is suspended.
