Add QCA_NL80211_VENDOR_SUBCMD_ADJUST_TX_POWER command
During high battery voltage scenario, higher MCS data rate leads to poor EVM accuracy which causes poor user experience. Hence to provide better user experience, EVM accuracy needs to be improved by adjusting TX power for MCS rate of specific band/radio chain. To achieve this, add a new vendor command to configure required parameters in the WLAN driver. Signed-off-by: Mukul Sharma <quic_mukul@quicinc.com>
