Add a hid_hw_may_wakeup() function, which is the equivalent of device_may_wakeup() for hid devices. In most cases this just returns device_may_wakeup(hdev->dev.parent), but for some ll-drivers this is not correct. E.g. usb_hid_driver instantiated hid devices have their parent set to the usb-interface to which the usb_hid_driver is bound, but the power/wakeup* sysfs attributes are part of the usb-device, which is the usb-interface's parent. For these special cases a new may_wakeup callback is added to hid_ll_driver, so that ll-drivers can override the default behavior.
