qcacmn: Support channel list update when afc_reg_no_action is set

In enterprise mode, when power event is received from Target, ACS is
not called and regulatory takes no action to AFC power event.
Hence, when host receives the event REG_AFC_EVENT_TIMER_EXPIRY with
subevent type SWITCH_TO_LPI or STOP_TX from FW as a response to payload
reset command from client application, the channel list is not updated
as 'afc_reg_no_action' is enabled.

To fix this issue and update the channel list, add reg txops to trigger
channel list update while processing REG_AFC_EVENT_TIMER_EXPIRY event
from FW when 'afc_reg_no_action' is set.

It is to be noted that 'afc_reg_no_action' should be set only in
enterprise mode.
