platform/x86: asus-wmi: Add quirk wmi_ignore_fan
[ Upstream commit c874b6de4cdfa2822a07b479887cd5f87fb5d078 ] Some laptops have a fan device listed in their ACPI tables but do not actually contain a fan. Introduce a quirk that can be used to override the fan detection logic. This was observed with a ASUS VivoBook E410MA running firmware E410MAB.304.
