[PATCH v6 0/6] Tracing cleanup and add mmio tracing

xe_trace.h is getting bloated. Group related events to their own
files. All bo, vm and vma related events have been moved to 
xe_trace_bo.h. GuC related trace events have been moved to
xe_trace_guc.h. Patches 1 and 2 splits the trace events into
seperate files.

In multi gpu environments, it is important to know the device from
which the event was triggered. Print the device id information along
with the trace information being printed. Patches 3, 4 and 5 make
changes to print the device id's if not already captured.

Mmio reg read writes are important tracing information that needs to be
captured and will be helpful in display debug. Patch 6 adds the reg
read/write tracing support.

Earlier versions of patch 6 can be found here:
v1: https://patchwork.freedesktop.org/series/119312/
v2: https://patchwork.freedesktop.org/series/132626/

v4: Fixes the review comments from Gustavo
v5: Fixes the kunit error reported.
v6: Remove unused string_helper inclusion in trace files and other 
    minor cleanups

Radhakrishna Sripada (6):
  drm/xe/trace: Extract bo, vm, vma traces
  drm/xe/trace: Extract guc related traces
  drm/xe/trace: Print device_id in xe_trace_bo events
  drm/xe/trace: Print device_id in xe_trace_guc events
  drm/xe/trace: Print device_id in xe_trace events
  drm/xe: Add reg read/write trace
