Introduce tracepoints to allow tracing the GLINK packets being exchanged
with other subsystems. This is useful for debugging both interaction
with remote processors and client driver issues, as well as tracking
latency through the communication stack.
Channel events are traced with both local and remote channel ids, as
well as the textual representation when possible. The channel ids are
useful when matching traces with traces from the firmware side logs,
while the textual representation is necessary to identify channels when
we're starting to trace an already running system.
