[ Upstream commit d196bbbc28fab82624f7686f8b0da8e8644b6e6a ]

clang warns:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_pp_smu.c:336:8:
warning: implicit conversion from enumeration type 'enum smu_clk_type'
to different enumeration type 'enum amd_pp_clock_type'
[-Wenum-conversion]
                                        dc_to_smu_clock_type(clk_type),
                                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_pp_smu.c:421:14:
warning: implicit conversion from enumeration type 'enum
amd_pp_clock_type' to different enumeration type 'enum smu_clk_type'
[-Wenum-conversion]

                                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are functions to properly convert between all of these types, use
them so there are no longer any warnings.

Fixes: a43913ea50a5 ("drm/amd/powerplay: add function get_clock_by_type_with_latency for navi10")
Fixes: e5e4e22391c2 ("drm/amd/powerplay: add interface to get clock by type with latency for display (v2)")
