drm/amd/display: move watermarks table to pp_smu

Browse source

[WHAT]
amdgpu_dm_smu_write_watermarks_table() pushes fixed dcn watermark
clock settings to the SMU on Navi1x. It belongs with the other
dc-pplib bridge code, so move it out of amdgpu_dm.c into
amdgpu_dm_pp_smu.c.

It is called from dm_resume(), so it becomes a plain exported function
declared in amdgpu_dm_pp_smu.h (now included by amdgpu_dm.c) instead of
STATIC_IFN_KUNIT in amdgpu_dm.h. Relocate its KUnit test from the
amdgpu_dm suite to the amdgpu_dm_pp_smu suite. No functional change.
