Clock pause message informs all devices on the bus that the active
manager having framer device pause the bus. This allows stopping the
clock to conserve power.
Clock is paused only if there are no active data channels on the bus
and no response is pending for any READ message.
Slimbus framework wakes up the controller using a wakeup function
pointer. Controller should then program the active framer to be out of
clock pause.
