drm/amd/pm: Fix clock reporting for SMUv13.0.6

Browse source

On SMU v13.0.6, effective clocks are reported by FW which won't exactly
match with DPM level. Report the current clock based on the values
matching closest to the effective clock. Also, when deep sleep is
applied to a clock, report it with a special level "S:" as in sample
clock levels below

S: 19Mhz *
0: 615Mhz
1: 800Mhz
2: 888Mhz
3: 1000Mhz
