Subject: [PATCH 5.6 205/254] drm/amd/powerplay: implement the is_dpm_running()

From: Prike Liang <Prike.Liang@....com>

commit 4ee2bb22ddb53a2eafc675690d0d67452029ca37 upstream.

As the pmfw hasn't exported the interface of SMU feature
mask to APU SKU so just force on all the features to driver
inquired interface at early initial stage.
