idpf: add mailbox access to read PTP clock time
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.
