[Intel-xe] [PATCH v2 0/4] Port CPU-GPU timestamp correlation to XE KMD

[Umesh Nerlige Ramappa]

This is a port of prior work from i915 to support fine-grained CPU-GPU
timestamp correlation. Prior work is linked in this issue:
https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/384

Mesa and Perfetto are the consumers for this and the issue documents the
need for higher accuracy in correlation. 

v2:
- Change commit headers to fixup!
- Fix kernel-doc errors
- Include review comments
