[PATCHv4] HID: sony: Enable Gasia third-party PS3 controllers

[Lauri Kasanen]

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: size 8 works.

v4:
- use size 8

v3:
- reuse the dummy heap buffer
- skip later checks if the earlier ones fail

v2:
- edited error messages
- use output_report

Original controllers still work fine after this change.
Some follow-up patches are on their way.
