HID: usbhid: add quirk for innomedia INNEX GENESIS/ATARI adapter

commit 9547837bdccb4af127528b36a73377150658b4ac upstream.

The (1292:4745) Innomedia INNEX GENESIS/ATARI adapter needs
HID_QUIRK_MULTI_INPUT to split the device up into two controllers
instead of inputs from both being merged into one.
