I guess, they map Z axis to be a wheel instead a wheel be a wheel like in the
0x030c case.

Could you add
{ HID_BLUETOOTH_DEVICE(USB_VENDOR_ID_APPLE, 0x030c),
  .driver_data = APPLE_MIGHTYMOUSE }
there and
HID_BLUETOOTH_DEVICE(USB_VENDOR_ID_APPLE, 0x030c)
to hid_blacklist in drivers/hid/hid-core.c and try? If the wheel is inverted
with your device, then you need also APPLE_INVERT_HWHEEL aswell.
