Subject: [PATCH 3005/4256] drm/amd/powerplay: custom peak clock freq for
navi10
v2:
add function smu_default_set_performance_level as default dpm level handler.
change function name smu_set_performance_level to smu_asic_set_performance_level
v1:
1.NAVI10_PEAK_SCLK_XTX 1830 Mhz
2.NAVI10_PEAK_SCLK_XT 1755 Mhz
3.NAVI10_PEAK_SCLK_XL 1625 Mhz
