Refactor firmware, serialization and command timeouts so that
HDD timeout are greater than serialization is greater than firmware
timeout.

The timeouts are defined considering below worst case delay in
firmware.
WMI_VDEV_START_REQUEST_CMDID	6 sec
WMI_VDEV_RESTART_REQUEST_CMDID	6 sec
WMI_VDEV_STOP_CMDID		2 sec
WMI_PEER_DELETE_CMDID		2 sec
WMI_PEER_ASSOC_CMDID		2 sec
WMI_PDEV_SET_HW_MODE_CMDID	2 sec
