[PATCH 0/3] drm/amd/display: use kunit/visibility.h for test helpers

[Albert Esteve]

amdgpu_dm grew its own STATIC_IFN_KUNIT / EXPORT_IF_KUNIT /
INLINE_IFN_KUNIT macros instead of using kunit/visibility.h. This
series switches the KUnit helpers over to the common API.

VISIBLE_IF_KUNIT is gated on CONFIG_KUNIT rather than
CONFIG_DRM_AMD_DC_KUNIT_TEST, so the helpers are non-static whenever
KUnit is enabled. EXPORT_SYMBOL_IF_KUNIT places the symbols in the
EXPORTED_FOR_KUNIT_TESTING namespace; the AMD DC test files import
that namespace with MODULE_IMPORT_NS().

INLINE_IFN_KUNIT is dropped rather than generalized. It was only used
on amdgpu_dm_fixpt_from_s3132(), inverted the original static inline,
and is unnecessary for tests in another translation unit.

Tested with:
  ./tools/testing/kunit/kunit.py run --arch=x86_64 \
    --kunitconfig=drivers/gpu/drm/amd/display/amdgpu_dm/tests

(CONFIG_GCOV omitted; it is not available on x86_64.)
