[PATCH] drm/amd/display: Export symbols for KUnit test modules

[Alex Hung <alex.hung@amd.com>]

Add missing EXPORT_IF_KUNIT() calls for amdgpu_dm_psr_set_event,
amdgpu_dm_ism_init, and amdgpu_dm_ism_fini so that the KUnit test
modules can resolve these symbols when built as modules, i.e.,
CONFIG_DRM_AMD_DC_KUNIT_TEST=m.

Fixes: 7c1bb28ce2f0 ("drm/amd/display: Add KUnit tests for amdgpu_dm_psr_set_event")
Fixes: 4db0dd9e5a63 ("drm/amd/display: Add more KUnit tests for amdgpu_dm_ism")
