Add a QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_THERMAL_CMD
to implement thermal mitigation. Different operations required to
implement this feature can be specified in
QCA_WLAN_VENDOR_ATTR_THERMAL_CMD_VALUE,
QCA_WLAN_VENDOR_ATTR_THERMAL_LEVEL.
Userspace requests the driver to enable/disable thermal mitigation
based on the thermal state of the device and wlan host performs the
required appropriate action. wlan host driver maps the thermal level
provided from userspace via vendor command to corresponding duty
cycle off percent value and duty cycle value,send
WMI_THERM_THROT_SET_CONF_CMDID cmd to FW.
Make changes to perform vendor command handling, mapping thermal level
to duty cycle value and communicating the thermal information to FW.
