drm/amd/display: Shorten KUnit exported symbol names

Browse Source 
The KUnit exported helpers

  amdgpu_dm_plane_fill_gfx9_plane_attributes_from_modifiers()
  amdgpu_dm_plane_fill_gfx12_plane_attributes_from_modifiers()

exceed MODULE_NAME_LEN and cause modpost to fail with:

  ERROR: modpost: too long symbol
  "amdgpu_dm_plane_fill_gfx9_plane_attributes_from_modifiers"

Shorten the helper names while preserving their functionality.
