[PATCH] drm/amdgpu: use dev_info to benifit mGPU case

[Quan, Evan]

[AMD Official Use Only - General]

Here "free PSP TMR buffer" seems having some special meanings (a marker that indicates suspending is on-going).
Better to redesign the prompts for suspending.
Anyway, the patch is reviewed-by: Evan Quan <evan.quan at amd.com>
