Subject: [PATCH] drm/amd/pp: Refine the output of pp_power_profile_mode on VI

In order to keep consist with Vega,
the output format of the pp_power_profile_mode would be
<integer>  <mode name string>< “*” if this is the current profile>:"detail settings"
and remove the "CURRENT" mode line.

for example:
NUM        MODE_NAME     SCLK_UP_HYST   SCLK_DOWN_HYST SCLK_ACTIVE_LEVEL     MCLK_UP_HYST   MCLK_DOWN_HYST MCLK_ACTIVE_LEVEL
