tools headers UAPI: Sync drm/i915_drm.h with the kernel sources

To pick the change in:

4ef10fe05ba0 ("drm/i915/perf: add new open param to configure polling of OA buffer")
11ecbdddf2f8 ("drm/i915/perf: introduce global sseu pinning")

That don't result in any changes in tooling, just silences this perf
build warning:

Warning: Kernel ABI header at 'tools/include/uapi/drm/i915_drm.h' differs from latest version at 'include/uapi/drm/i915_drm.h'
