platform/x86: asus-wmi: add support for vivobook fan profiles

Browse Source 
Add support for vivobook fan profiles wmi call on the ASUS VIVOBOOK
to adjust power limits.

These fan profiles have a different device id than the ROG series
and different order. This reorders the existing modes.

As part of keeping the patch clean the throttle_thermal_policy_available
boolean stored in the driver struct is removed and
throttle_thermal_policy_dev is used in place (as on init it is zeroed).
