drm/amd/pm: Add support for DPM policies

Browse source

Add support to set/get information about different DPM policies. The
support is only available on SOCs which use swsmu architecture.

A DPM policy type may be defined with different levels. For example, a
policy may be defined to select Pstate preference and then later a
pstate preference may be chosen.
