Jiri Kosina 85cbea3952 USB HID: Logitech MX3000 keyboard needs report descriptor quirk 
Logitech MX3000 contains report descriptor which doesn't cover usages
above 0x28c, but emits such usages. Report descriptor needs fixing
in the very same way as with receivers shipped with S510 keyboards.

This patch also adds a few mappings for multimedia keys that S510 didn't
emit.
