[PATCH 066/138] drm/amd/powerplay: set defalut dpm table for smu

[Huang Rui <ray.huang-5C7GfCeVMHo@public.gmane.org>]

From: Likun Gao <Likun.Gao@amd.com>

Add smu_set_default_dpm_table function to set dpm table for smu11.
Modified the sequence to populate smc pptable, as it should be done after
related dpm feature is enabled.
