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.
