amdgpu/pm: Powerplay API for smu , updates to some pm functions

v3: updated to include new clocks od_vddgfx_offset, od_cclk
    Context mismatch with revision v3 to patch 0003

Modified Functions
  smu_sys_set_pp_table()        - modifed signature to match Powerplay API set_pp_table
  smu_force_performance_level() - modifed arg0 to match Powerplay API force_performance_level
  smu_od_edit_dpm_table()       - modifed arg0 to match Powerplay API odn_edit_dpm_table

Other Changes
  smu_od_edit_dpm_table()       - removed call to task(READJUST_POWER_STATE) after COMMIT_TABLE,
                                  now handled in calling function
  amdgpu_set_power_dpm_force_performance_level() - now checks thermal for swsmu systems before trying to change level
  amdgpu_set_pp_od_clk_voltage() - now attempts to set fine_grain_clock_vol before swsmu edit dpm table
