smu.ppt_funcs is only initialized for ASICs supporting SW SMU.
On a Hawaii ASIC, attempting to access the udev attribute
ATTRS{power_dpm_state} will cause a null pointer deref in
amdgpu_get_dpm_state() because of this.
Fix by checking if SW SMU is supported first.

Under vega10 virtualuzation, smu ip block will not be added.
Therefore, we need add pp clk query and force dpm level function
at amdgpu_virt_ops to support the feature.
v2: add get_pp_clk existence check and use kzalloc to allocate buf
v3: return -ENOMEM for allocation failure and correct the coding style

Add sys interface to set socclk, fclk and dcefclk for smu.
Add feature_mask parameter for smu_upload_dpm_level as socclk, fclk and
dcefclk have dependency, without feature_mask to point out specific clk
will make it fail to set some clk.
Fix the function of smu_unforce_dpm_levels.
