Revert "HID: dragonrise: fix HID Descriptor for 0x0006 PID"

This reverts commit 18339f5 ("HID: dragonrise: fix HID...") because it breaks certain dragonrise 0079:0006 gamepads. While it may fix a breakage caused by commit 79346d6 ("HID: input: force generic axis to be mapped to their user space axis"), it is probable that the manufacturer released different hardware with the same PID so this fix works for only a subset and breaks the other gamepads sharing the PID. What is needed is another more generic solution which fixes 79346d6 ("HID: input: force generic axis ...") breakage for this controller: we need to add an exception for this driver to make it keep the old behaviour previous to the initial breakage (this is done in patch 2 of this series).
