HID: kye: Rewrite tablet descriptor fixup routine

Genius digitizer tablets send incorrect (vendor-defined) report descriptors
by default. Descriptors for several models were added to override original
ones. Since they share the same structure and are handled by the same
Windows driver routine, extract the descriptor template and dynamic
parameters for easier new device adoption.
