From: Jiri Kosina <jikos@jikos.cz>

I have a bugreport that scrollwheel of bluetooth version of apple
mightymouse doesn't work.  The USB version of mightymouse works, as there
is a quirk for handling scrollwheel in hid/usbhid for it.

Now that bluetooth git tree is hooked to generic hid layer, it could easily
use the quirks which are already present in generic hid parser, hid-input,
etc.

Below is a simple patch against bluetooth git tree, which adds quirk
handling to current bluetooth hidp code, and sets quirk flags for device
0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.
