regulator: cpr3: Update temp based adjustments config

Browse source 
Temp_adj_en instantaneously reduces the voltage and quotient
when temperature enters into corresponding band which may cause
an aggressive reduction in voltage. Avoid this by not configuring
temp_adj_en bit, this only reduces the quotient and allows CPR to
react to the reduced quotient. Use temp_adj_en bit only when both
temperature based and core count based adjustments are desired.
