[PATCH] hid: usbhid: Enable remote wake-up based on device configuration

[ryan]

According to the USB protocol, the host should automatically
adapt the remote wake-up function based on the configuration
descriptor reported by the device, rather than only the default
keyboard support. Therefore, it's necessary to support other hid
devices, such as digital headsets,mice,etc.
