[PATCH] amdgpu/pm: Don't show `smartshift_*_power` files for APUs

[Mario Limonciello]

`smartshift_*_power` files are showing up on some OEM programs on
the APU instead of the dGPU.

Adjust the logic to the function `ss_power_attr_update`
to detect whether or not the attributes should be exported.

The existing checks that are dropped are already included in
`amdgpu_device_support_smart_shift`, so this can be simplified.
This causes attributes to not be shown on APUs.
