Commit b6cc0ba2cbf4 (HID: add support for Apple Magic Keyboards)
backported support for the Magic Keyboard over Bluetooth, but did not
add the BT_VENDOR_ID_APPLE to hid_have_special_driver[] so the hid-apple
driver is never loaded and Fn key does not work at all.

Adding BT_VENDOR_ID_APPLE to hid_have_special_driver[] is not needed
after commit e04a0442d33b (HID: core: remove the absolute need of
hid_have_special_driver[]), so 4.16 kernels and newer does not need it.

Benjamin, thank you for your help with this.

I believe this is needed for both linux-4.14.y and linux-4.9.y.
