platform/x86: ideapad-laptop: Fix interrupt storm on fn-lock toggle on some Yoga laptops

Commit 3ae86d2d

 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock
LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops
to manually toggle the fn-lock LED because the EC does not do it itself.
However, the same WMI ID is also sent on some Yoga laptops. Here, setting
the fn-lock state is not valid behavior, and causes the EC to spam
interrupts until the laptop is rebooted.

Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to
manually set the LED on models on this list.
