drm/amd/pm: setup APU dpm clock table in SMU HW initialization

As the dpm clock table is needed during DC HW initialization.
And that (DC HW initialization) comes before smu_late_init()
where current APU dpm clock table setup is performed. So, NULL
pointer dereference will be triggered. By moving APU dpm clock
table setup to smu_hw_init(), this can be avoided.
