[PATCH v3 00/10] Add PM policy interfaces

[Lijo Lazar]

This series adds APIs to get the supported PM policies and also set them. A PM
policy type is a predefined policy type supported by an SOC and each policy may
define two or more levels to choose from. A user can select the appropriate
level through amdgpu_dpm_set_pm_policy() or through sysfs node pm_policy. Based
on the specific PM functional area, multiple PM policies may be defined for an
SOC For ex: a policy may be defined to set the right setting for XGMI per link
power down feature and another may be defined to select the SOC Pstate
preferences.
 
Presently, XGMI PLPD and SOC Pstate policy types are supported. It also removes
the legacy sysfs interface to set XGMI PLPD as it is not used any client like
SMI tool.

v2:
 Add NULL checks to avoid access on SOCs which don't support any policy.

v3:
 Rebase and add documentation patch
