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 and adds a new
full speed mode available on these laptops.
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).
Changelog:
- V1
- Fixes grammar in description
- reorders macros
- adds throttle_thermal_policy_max_mode() helper function
- V2
- removes unnecessary braces in throttle_thermal_policy_max_mode()
