drm/amd/pm: hide pp_table sysfs on APUs

Browse source

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.
