tools headers uapi: Update drm/i915_drm.h

To get the changes in:

  e46c2e99f6 ("drm/i915: Expose RPCS (SSEU) configuration to userspace (Gen11 only)")

That don't cause changes in the generated perf binaries.

To silence 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'

* Context SSEU programming
*
* It may be necessary for either functional or performance reason to configure
* a context to run with a reduced number of SSEU (where SSEU stands for Slice/
* Sub-slice/EU).
*
* This is done by configuring SSEU configuration using the below
* @struct drm_i915_gem_context_param_sseu for every supported engine which
* userspace intends to use.
*
* Not all GPUs or engines support this functionality in which case an error
* code -ENODEV will be returned.
*
* Also, flexibility of possible SSEU configuration permutations varies between
* GPU generations and software imposed limitations. Requesting such a
* combination will return an error code of -EINVAL.
*
* NOTE: When perf/OA is active the context's SSEU configuration is ignored in
* favour of a single global setting.
