drm/amd/powerplay: Add read_sensor() callback to hwmgr (v3)
Provides standardized interface to read various sensors.
The API is extensible (by adding to the end of the
amd_pp_sensors enumeration list.
Support has been added to Carrizo/smu7
(v2) Squashed the two sensor patches into one.
(v3) Updated to apply to smu7_hwmgr instead
