Subject: [PATCH] drm/amd/pm: enable more Pstates profile levels for yellow_carp

This patch enables following UMD stable Pstates profile levels for power_dpm_force_performance_level interface.

- profile_peak
- profile_min_mclk
- profile_min_sclk
- profile_standard

The macro 'SMU_13_VCLK_SHIFT' can be shared by SMU13 APUs and is defined in smu_v13_0.h in the patch for SMU v13.0.4.
So, it should not need this definition again. thanks.
