amdgpu/pm: Powerplay API for smu , changed 6 dpm reset functions to use API

Modified Functions
  smu_set_xgmi_pstate()       - modifed arg0 to match Powerplay API set_xgmi_pstate
  smu_mode2_reset()           - modifed arg0 to match Powerplay API asic_reset_mode_2
  smu_switch_power_profile()  - modifed arg0 to match Powerplay API switch_power_profile
  smu_set_mp1_state()         - modifed arg0 to match Powerplay API set_mp1_state
  smu_set_df_cstate()         - modifed arg0 to match Powerplay API set_df_cstate
  smu_enable_mgpu_fan_boost() - modifed arg0 to match Powerplay API enable_mgpu_fan_boost

Other Changes
  added above smu reset Powerplay functions to swsmu_dpm_funcs
  removed special smu handling of above functions and called through Powerplay API
