HID: Add Apple Touchbar on T2 Macs in hid_have_special_driver list
The touchbar on Apple T2 Macs has 2 modes, one that shows the function
keys and other that shows the media controls. The user can use the fn
key on his keyboard to switch between the 2 modes.
On Linux, if people were using an external keyboard or mouse, the
touchbar failed to change modes on pressing the fn key with the following
in dmesg :-

Add the USB IDs of the touchbar found in T2 Macs to HID have special
driver list to fix the issue.
