[PATCH 4/4] drm/amd/pm: restore user PPT limits after GPU reset

GPU reset reinitializes PMFW and reloads the platform power table. The
saved user policy remains valid, but suspend-only restore does not run
because adev->in_suspend is clear.

Restore the active PPT policy from SMU late initialization while the
device is in reset recovery. Route each value through the common range
validation and ASIC setter before updating PMFW.
