amdgpu/pm: Powerplay API for smu , changes to clock and profile mode functions

v3: updated to include new clocks vclk, dclk, od_vddgfx_offset, od_cclk
    Added forward declaration for function smu_force_smuclk_levels to resolve clash with other commits
    Resolved context clashes with other commits and v3 updates to patches 0003, 0004
v2: fix errors flagged by checkpatch

New Functions
  smu_bump_power_profile_mode() - changes profile mode assuming calling function already has mutex
  smu_force_ppclk_levels()      - accepts Powerplay enum pp_clock_type to specify clock to change
  smu_print_ppclk_levels()      - accepts Powerplay enum pp_clock_type to request clock levels
  amdgpu_get_pp_dpm_clock()     - accepts Powerplay enum pp_clock_type to request clock levels and allows
                                  all the amdgpu_get_pp_dpm_$CLK functions to have a single codepath
  amdgpu_set_pp_dpm_clock()     - accepts Powerplay enum pp_clock_type to set clock levels and allows
                                  all the amdgpu_set_pp_dpm_$CLK functions to have a single codepath

Modified Functions
  smu_force_smuclk_levels        - changed function name to make clear difference to smu_force_ppclk_levels
  smu_force_ppclk_levels()       - modifed signature to implement Powerplay API force_clock_level
                                 - calls smu_force_smuclk_levels
  smu_print_smuclk_levels        - changed function name to make clear difference to smu_print_ppclk_levels
  smu_print_ppclk_levels()       - modifed signature to implement Powerplay API force_clock_level
                                 - calls smu_print_smuclk_levels
  smu_sys_get_gpu_metrics        - modifed arg0 to match Powerplay API get_gpu_metrics
  smu_get_power_profile_mode     - modifed arg0 to match Powerplay API get_power_profile_mode
  smu_set_power_profile_mode     - modifed arg0 to match Powerplay API set_power_profile_mode
                                 - removed arg lock_needed, mutex always locked, internal functions
                                   can call smu_bump if they already hold lock
  smu_switch_power_profile       - now calls smu_bump as already holds mutex lock
  smu_adjust_power_state_dynamic - now calls smu_bump as already holds mutex lock
  amdgpu_get_pp_od_clk_voltage   - uses smu_print_ppclk_levels
  amdgpu_{set,get}_pp_dpm_$CLK   - replace logic with call helper function amdgpu_{set,get}_pp_dpm_clock()
                                   CLK ={sclk, mclk, socclk, fclk, dcefclk, pci, vclkd, dclk}

Other Changes
  added 5 smu Powerplay functions to swsmu_dpm_funcs
  removed special smu handling in pm functions and called through Powerplay API
