qcacld-3.0: Add INI to configure thermal action

There is customer requirement that once wifi chip overheat,
we should switch the tx chain mask to 1X1 to cool down the
chip instead of halting the tx completely.
Add new INI gThermalMgmtAction to configure thermal mgmt action
with default 0. The valid thermal mgmt action INI value is defined
as enum thermal_mgmt_action_code. To set it to 3 -
THERMAL_MGMT_ACTION_CHAINSCALING to meet customer requirement.
