In the AFC Enterprise mode, the AFC response-payload may need to be
reset from host. The payload reset is done by sending
WMI_SERVICE_AFC_RESET_SUPPORT subtype in the WMI_AFC_CMD to the target.
In response, the target sends the WMI_AFC_EVENT_TIMER_EXPIRY event with
WMI_AFC_EXPIRY_EVENT_SWITCH_TO_LOW_POWER_MODE (in indoor deployment) or
WMI_EXPIRY_EVENT WMI_AFC_EXPIRY_EVENT_STOP_TX (in outdoor deployment)
event subtype to the host.
Earlier, the WMI_AFC_EVENT_TIMER_EXPIRY event was sent only in
non-enterprise mode. Now, since it can be sent for both enterprise and
non-enterprise mode, we need to take care of 'afc_reg no action",
which is mandatory in case of enterprise mode.
Therefore, implement the following changes:
1) Call trigger_acs_for_afc only if afc_reg_no_action is not set.
2) Send the AFC payload reset event during SWITCH_TO_LPI and STOP_TX
event, and free the AFC payload received from the target.
3) Add APIs to register a callback to send the AFC payload reset event.
