Subject: [PATCH] platform/x86: asus-wmi: Add quirk for ASUS Vivobook S14

The ASUS Vivobook S14 will have wifi disabled on boot as well as
resumption from suspend if the asus-wmi driver invokes rfkill functions.

This patch disables asus-wmi's rfkill usage to prevent the wifi card
from being software disabled.
