APUs use firmware-owned DPM tables and do not support replacement through
pp_table. Generic callbacks can nevertheless expose the sysfs file and
accept an upload before resetting the power management stack.
Treat pp_table as unsupported on APUs. Use the same platform check in the
get and set paths to hide the file and reject uploads.
Fixes: 289921b03f ("drm/amd/powerplay: implement sysfs of pp_table for smu11 (v2)")
