firewire: core: add tracepoints event for self_id_sequence

Browse source

It is helpful to trace the content of self ID sequence when the core
function building bus topology.

This commit adds a tracepoints event fot the purpose. It seems not to
achieve printing variable length of array in print time without any
storage, thus the structure of event includes a superfluous array to store
the state of port. Additionally, there is no helper function to print
symbol array, thus the state of port is printed as raw value.
