qcacmn: Handle Umac reset for MLO case

1. Add an API to process trigger_umac_recovery T2H message.
2. Synchronize do_pre_reset, do_post_reset_start, do_post_reset_complete
   messages for all the SOCs and then process these messages in the host.
3. Synchronize pre_reset_done, post_reset_start_done,
   post_reset_complete_done for all the SOCs before sending it to FW.
4. Add a new state in host for trigger_umac_recovery message.
   Ignore back to back trigger_umac_recovery messages received from FW.
