platform/x86: ideapad-laptop: support for more special keys in WMI

The event data of the WMI event 0xD0, which is assumed to be the
fn_lock, is used to indicate several special keys on newer Yoga 7/9
laptops.

The notify_id 0xD0 is non-unique in the DSDT of the Yoga 9 14IAP7, this
causes wmi_get_event_data() to report wrong values.
Port the ideapad-laptop WMI code to the wmi bus infrastructure which
does not suffer from the shortcomings of wmi_get_event_data().
