505bc983bf drm/amd/powerplay: make sure VCE is disabled by default 
This patch is a port of similar patch for amdgpu
when PP is disabled. Since the code flow is little
different when PP is enabled, we need to make sure
the patch is applied for PP enabled path as well.

With the current code, when we boot with the amdgpu
driver enabled and loaded, the VCE also automatically
remains enabled since bootup. This can be verified from
the output of amdgpu_pm_info. It does not matter whether
we boot into command line directly or into X, the VCE
stays enabled the entire time.

This patch addresses the issue and makes sure that
VCE is turned on only during playback, and remains
disabled otherwise.

eafc9c2704 amdgpu: use NULL instead of 0 for pointer 
In the AMD powerplay driver, a pointer is checked for validity by
comparing against an integer '0', which causes a harmless warning
when building with "make W=1":

drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/processpptables.c:1502:16: error: ordered comparison of pointer with integer zero [-Werror=extra]

This changes the code to the more conventional "if (pointer)" check.

0a81a87c98 drm/amd/powerplay: remove useless soft pptable in Asic related backend 
The soft pptable was used for re-uploading pptable as cache, but since
previous commits, the generic codes for uploading pptable are used and
backend is released during resetting powerplay. So it becomes redundance.

2. Populate SMC ACPI minimum voltage using VBIOS boot SCLK and MCLK

When static voltage is configured as VDDCI, driver still tries to program
a voltage for MM minVoltage using VDDC-VDDCI delta requirement.
minVoltage should be set as boot up voltage.
