I wonder if driver core should be responsible for clearing wake irq and
also for clearing wakeup flag.

AFAICU, wakeup flag is deleted when struct device is deleted, hence,
device_init_wakeup() call may not be required in .remove(). But,
dev_pm_clear_wake_irq() can be moved to driver core.

Currently the lifecycle of struct wakeup_source is not necessarily
the same as the lifecycle struct device. I believe net and usb drivers
at least allocate it dynamically.
