Jiri Kosina af9e0eacdc HID: add full support for Genius KB-29E 
Genius KB-29E has broken report descriptor, which causes some of the
Consumer usages to appear incorrectly as Button usages. We fix it by
fixing the report descriptor before it is being parsed.

Also a few of the keys violate the HUT standard, so they need a special
handling. They currently fall into "Reserved" range as per HUT 1.12.
