Subject: [PATCH 6/7] drm/amd/powerplay: Use proper enums in vega20_print_clk_levels

clang warns:

drivers/gpu/drm/amd/amdgpu/../powerplay/vega20_ppt.c:995:39: warning:
implicit conversion from enumeration type 'PPCLK_e' to different
enumeration type 'enum smu_clk_type' [-Wenum-conversion]
                ret = smu_get_current_clk_freq(smu, PPCLK_SOCCLK, &now);
                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~

                ret = smu_get_current_clk_freq(smu, PPCLK_FCLK, &now);
                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../powerplay/vega20_ppt.c:1031:39: warning:

enumeration type 'enum smu_clk_type' [-Wenum-conversion]
                ret = smu_get_current_clk_freq(smu, PPCLK_DCEFCLK, &now);
                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~

The values are mapped one to one in vega20_get_smu_clk_index so just use
the proper enums here.
