drm/amd: Drop unnecessary calls to smu_dpm_set_vpe_enable()

smu_hw_init() and smu_hw_fini() call smu_dpm_set_vpe_enable() for
APUs as part of startup and teardown.  These calls however are
not necessary because vpe_hw_init()/vpe_hw_fini() will call at
init/fini:

```
vpe_hw_init() / vpe_hw_fini()
  amdgpu_device_ip_set_powergating_state()
    vpe_set_powergating_state()
      amdgpu_dpm_enable_vpe()
        amdgpu_dpm_set_powergating_by_smu()
          smu_dpm_set_power_gate()
            smu_dpm_set_vpe_enable()
```

Drop the extra calls.
