Regression fix for powerplay on some iceland boards.

* 'drm-fixes-4.9' of git://people.freedesktop.org/~agd5f/linux:
  drm/amd/powerplay: implement get_clock_by_type for iceland.
  drm/amd/powerplay/smu7: fix checks in smu7_get_evv_voltages (v2)
  drm/amd/powerplay: update phm_get_voltage_evv_on_sclk for iceland
  drm/amd/powerplay: propagate errors in phm_get_voltage_evv_on_sclk
