Hello,

This adds support for the Flydigi Apex 5 controller to the xpad kernel module. This has been tested as part of: https://github.com/paroj/xpad/pull/328

This patch is very small and simple, it simply white lists the controller so it can be used. The trigger and stick mappings are none standard, but SDL has the correct mappings already shipped so it's not a problem in Steam or games I've tried.

Here is the patch:
