Subject: [PATCH] Documentation/gpu: Remove duplicate kernel-doc exports in drm-uapi.rst

Eliminate redundant `:export:` kernel-doc directive in
Documentation/gpu/drm-uapi.rst to fix duplicate C declaration warnings
during Sphinx builds.

warning before this patch:

  WARNING: Duplicate C declaration, also defined at gpu/drm-kms:35
  Declaration is '.. c:function:: const struct drm_format_info *
  drm_format_info (u32 format)'. [duplicate_declaration.c]

The removed export was already documented elsewhere, so this patch
does not remove any meaningful documentation. Post-change, both
`make htmldocs` and targeted builds with `make htmldocs
SPHINXDIRS=Documentation/gpu`

complete cleanly without warnings.

Based on commit 47a8d4b89844
