Input: cyttsp4 - kill 'defined but not used' compiler warnings

If both CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME are unset:

drivers/input/touchscreen/cyttsp4_core.c:1556: warning: ‘cyttsp4_core_sleep’ defined but not used
drivers/input/touchscreen/cyttsp4_core.c:1634: warning: ‘cyttsp4_core_wake’ defined but not used

Move cyttsp4_core_sleep(), cyttsp4_core_wake(), and cyttsp4_core_wake_()
(which is called from cyttsp4_core_wake() only) inside the existing section
protected by #if defined(CONFIG_PM_SLEEP) || defined(CONFIG_PM_RUNTIME)
