Newer asics require that the dpm be initialized prior to the other engines in order for clockgating to work properly. The tricky part is that other aspects of dpm are required at later stages (e.g., after displays are enumerated). This patch set reworks the power management init flow to accomodate the requirements of newer hardware. Most of the pm init/fini/suspend/resume flow has now moved into the asic specific functions. As a result, dpm now initializes reliably on CIK parts and clockgating on these parts now works and is enabled by default. Powergating support for CIK parts is also improved, but is not yet ready to be enabled by default. I think it's now safe to enable dpm by default on CIK parts.
