[ Upstream commit 895085ec3f2ed7a26389943729e2904df1f88dc0 ]
When changing the thermal policy using the platform profile API, a Vivobook thermal policy is stored in throttle_thermal_policy_mode.
However everywhere else a normal thermal policy is stored inside this variable, potentially confusing the platform profile.
Fix this by always storing normal thermal policy values inside throttle_thermal_policy_mode and only do the conversion when writing the thermal policy to hardware. This also fixes the order in which throttle_thermal_policy_switch_next() steps through the thermal modes on Vivobook machines.
