HID: lenovo: Restrict detection of patched firmware only to USB cptkbd
Commit 46a0a2c96f0f ("HID: lenovo: Detect quirk-free fw on cptkbd and stop applying workaround") introduced a regression for ThinkPad TrackPoint Keyboard II which has similar quirks to cptkbd (so it uses the same workarounds) but slightly different so that there are false-positives during detecting well-behaving firmware. This commit restricts detecting well-behaving firmware to the only model which known to have one and have stable enough quirks to not cause false-positives.
