[PATCH] HID: usbhid: set mouse as a wakeup resource

[Richard Gong]

USB HID transport layer doesn't set mouse as a wakeup resource by default
so user can't wake system from s0i3 using wired USB mouse. However, users
can wake the same system from s0i3 with the same wired USB mouse
on Windows.

To work around this wakeup issue on Linux, the user must manually enable
wakeup via the following command:
	echo enabled > /sys/bus/usb/device/*/power/wakeup

The mouse is set to wake resource by default to ensure the same behavior
across operating systems.
