[Intel-gfx] [PATCH] drm/i915: fix Sphinx build duplicate label warning

[Jani Nikula]

Fix the warning caused by enabling the autosectionlabel extension in the
kernel Sphinx build:

Documentation/gpu/i915.rst:610: WARNING: duplicate label
gpu/i915:layout, other instance in Documentation/gpu/i915.rst

In the warning message, Sphinx is unable to reference the labels in
their true locations in the kernel-doc comments in source. In this case,
there's "Layout" sections in both gt/intel_workarounds.c and
i915_reg.h. Rename the section in the latter to "File Layout".

Fixes: 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst")
