Subject[PATCH] HID: sony: Enable Gasia third-party PS3 controllers
Without this, my "Gasia Co.,Ltd PS(R) Gamepad" would not send
any events. Now everything works including the leds.

Based on work by Andrew Haines and Antonio Ospite.

Antonio's original approach was not enough; it enabled the events,
but only for a few seconds, then the controller timed out and sent
no more. Andrew's did more than was necessary. This is a combination
of the two, against Linus' git.
