[PATCH 06/10] drm/amd/pp: Unified to ctrl autowattman/profile mode

[Rex Zhu]

Add a common hw interface to ctrl autowattman feature and
restore power profile mode.

when autowattman enabled, start the wattman queue when
power state is set. disable this feature when suspend/
enter manual mode.

when autowattman not support, just restore default power
profile mode in auto dpm level if it was changed.

FreeSync is enabled, disable or not set power profile mode.
