platform/x86: ideapad-laptop: add missing Ideapad Pro 5 fn keys

The scancodes for the Mic Mute and Airplane keys on the Ideapad Pro 5
(14AHP9 at least, probably the other variants too) are different and
were not being picked up by the driver. This adds them to the keymap.

Apart from what is already supported, the remaining fn keys are
unfortunately producing windows-specific key-combos.
