Subject: [PATCH 3/8] amdgpu/pm: Powerplay API for smu , changed 6 pm hwmon fan functions to use API
 
Modified Functions
  smu_set_fan_speed_rpm()     - modifed arg0 to match Powerplay API set_fan_speed_rpm
  smu_get_fan_control_mode()  - modifed signature to match Powerplay API get_fan_control_mode
  smu_set_fan_control_mode()  - modifed signature to match Powerplay API set_fan_control_mode
  smu_get_fan_speed_percent() - modifed signature to match Powerplay API get_fan_speed_percent
  smu_set_fan_speed_percent() - modifed signature to match Powerplay API set_fan_speed_percent
  smu_get_fan_speed_rpm()     - modifed arg0 to match Powerplay API get_fan_speed_rpm

Other Changes
  added 6 above smu fan Powerplay functions to swsmu_dpm_funcs
  removed special smu handling of above functions and called through Powerplay API
