This adds support for CLOCKSYNC SyS-T packets, that establish correlation
between the transport clock (STP timestamps) and SyS-T timestamps. These
packets are sent periodically to allow the decoder to keep both time
sources in sync.

This adds support for MIPI SyS-T protocol as specified in an open
standard [1]. In addition to marking message boundaries, it also
supports tagging messages with the source UUID, to provide better
distinction between trace sources, including payload length and
timestamp in the message's metadata.
This driver adds attributes to STP policy nodes to control/configure
these metadata features.
