drm/amd/powerplay: add basic powerplay framework
amdgpu_pp_ip_funcs is introduced to handle the two code paths, the legacy one and the new powerplay implementation. CONFIG_DRM_AMD_POWERPLAY kernel configuration option is introduced for the powerplay component. v4: squash in fixes v3: register debugfs file when powerplay module enable v2: add amdgpu_ucode_init_bo in hw init when amdgpu_powerplay enable.
