drm/amdgpu: disable runtime pm on several sienna cichlid cards(v2)

Browse Source 
[ Upstream commit d1acd68b2b8924c804e1e3cc1bc5fa4d6b76176c ]

Disable runtime power management on several sienna cichlid
cards, otherwise SMU will possibly fail to be resumed from
runtime suspend. Will drop this after a clean solution between
kernel driver and SMU FW is available.
