touch: Fix Touch_to_wake during RBSC mode

Calling enable_irq_wake() causes suspend_device_irqs() to treat the
given IRQ in a special way.the IRQ remains enabled, by on the first
interrupt it will be disabled, marked as pending and "suspended"
so that it will be re-enabled by resume_device_irqs()
during the subsequent system resume.
