Takashi Sakamoto fef4e61b0b ALSA: firewire-lib: extend tracepoints event including CYCLE_TIME of 1394 OHCI
A commit baa914cd81 ("firewire: add kernel API to access CYCLE_TIME
register") allow unit drivers to read CYCLE_TIME of 1394 OHCI controller.
The value expresses monotonic time with 42.195 Mhz resolution and wrapping
around every 128 seconds. The controller uses the time to govern
isochronous cycle.

This commit extends tracepoints event including the value so that event
parser can compute gap between current isochronous cycle and the latest
isochronous cycle in which packet is processed (in IR context) or scheduled
(in IT context). It loses backward compatibility to former format of the
tracepoints event.
