This patch (as1365) enables remote wakeup by default for USB keyboard
devices. Keyboards in general are supposed to be wakeup devices, but
the correct place to enable it depends on the device's bus; no single
approach will work for all keyboard devices. In particular, this
covers only USB keyboards (and then only those supporting the boot
protocol).

This patch is necessary in view of the preceding patch (3/6) in this
series, which disables remote wakeup by default for all USB devices.
