Subject: [PATCH] HID: hid-debug: add missing evdev and usage codes


Hid-debug's rdesc output for a game controller contained a few question
marks and numeric IDs instead of the expected descriptive names.

This happens because hid-debug's mapping data is missing a few HID
usages supported by hid-input.

Add missing codes for LEDs, simulator axis and gamepad buttons.
