drm/amdgpu/pm: fix powerplay OD interface

commit d5c7255dc7ff6e1239d794b9c53029d83ced04ca upstream.

The overclocking interface currently appends data to a
string.  Revert back to using sprintf().

Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1774
Fixes: 6db0c87a0a8ee1 ("amdgpu/pm: Replace hwmgr smu usage of sprintf with sysfs_emit")
