drm/amd/pm: derive stable PPT limits from PPTable
GetPptLimit reports mutable PMFW runtime state. Using that value for
static capabilities causes two externally visible problems:
- A userspace override changes the default reported through hwmon.
- A firmware reset changes the advertised minimum or maximum range.
Derive platform defaults and supported ranges from the driver PPTable
for Sienna Cichlid, Navi10, Arcturus, and Aldebaran. Reserve PMFW queries
for the effective current limit.
Runtime policy can no longer redefine immutable platform capabilities.
