[why & how]
we have two SSC_En:
we get ssc_info from dce_info for MPLL_SSC_EN.
we used to call VBIOS cmdtbl's smu_info's SS persentage for DPRECLK SS info,
is used for DP AUDIO and VBIOS' smu_info table was from
systemIntegrationInfoTable.
since dcn35 VBIOS removed smu_info, driver need to use integrationInfotable
directly.
