habanalabs/gaudi: use COMMS to reset device / halt CPU

This is needed because legacy FW 'communication' protocol will soon
become obsolete.
Because COMMS is a boot protocol, communicating through it is supported
only until Linux is loaded to the device CPU, where in that case we
will fallback to the former implementation.
