> When the access to read PTP clock is specified as mailbox, the driver needs to
> send virtchnl message to perform PTP actions. Message is sent using
> idpf_mbq_opc_send_msg_to_peer_drv mailbox opcode, with the parameters
> received during PTP capabilities negotiation.
> 
> Add functions to recognize PTP messages, move them to dedicated secondary
> mailbox, read the PTP clock time and cross timestamp using mailbox
> messages.
