HID: Add WinWing Orion2 throttle support

WinWing Orion2 throttle works with Linux out of box,
but the kernel sees only 16 of 47 buttons on the throttle base.

This module enables all buttons, and also adds LED controls.

Button numbers 0 .. 63 on Orion2 are reserved for throttle grip;
the throttle base buttons have numbers 64 .. 110.

Linux kernel HID subsystem only supports up to 80 buttons.

Remap throttle base buttons to numbers 32 .. 78,
reserving only numbers 0 .. 31 for buttons on the grip handle.

Changes since v2:
   - Fixed automatic line wraps added by mail client

Changes since v1:
   - Fixed formatting of descriptor byte array;
   - Using product codes of Winwing grips in config.
