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
