[PATCH] drm/amd/pp: Implement get_power_profile_mode on smu7

[Rex Zhu]

Use can get smu7 profile pamameters through sysfs

cat pp_power_profile_mode

NUM        MODE_NAME UP_HYST DOWN_HYST ACTIVE_LEVEL
  0 3D_FULL_SCREEN*:   0       100           30
  1   POWER_SAVING :  10         0           30
  2       COMPUTER :   0         5           30
  3         CUSTOM :   0         0            0
