drm/i915/guc: Add GuC <-> kernel time stamp translation information

Browse source

It is useful to be able to match GuC events to kernel events when
looking at the GuC log. That requires being able to convert GuC
timestamps to kernel time. So, when dumping error captures and/or GuC
logs, include a stamp in both time zones plus the clock frequency.
