drm/doc: fix duplicate declaration warning

We have duplicate kernel-doc directives for the same struct, leading to:

/home/jani/src/linux/Documentation/gpu/driver-uapi.rst:2279: WARNING: Duplicate C declaration, also defined at rfc/i915_scheduler:3.
Declaration is '.. c:struct:: i915_context_engines_parallel_submit'.

Use the Sphinx C domain namespace for the rfc document to fix this.
