TAS state switching mechanism now incorporates the TX ratio as a decision parameter. The average power calculation has been improved by using a higher resolution conversion from dBm to linear. During scan or MCC operations, TAS state is forced to static SAR and suspend the average power calculation. Additionally, TAS window size depends on the regulatory domain and band to ensure compliance. TAS is enabled when permitted by the regulatory domain and is currently supported on the 8852CE. For debugging, add a flag to disable_dm that can stop TAS mechanism.
