Use debugfs API directly instead of drm middle layer.
This also includes following debugfs file output changes:
1 amdgpu_evict_vram/amdgpu_evict_gtt output will not contain any braces.
e.g. (0) --> 0
2 amdgpu_gpu_recover output will print return value of
amdgpu_device_gpu_recover() instead of not so important "gpu recover"
message.
v2: * checkpatch.pl: use '0444' instead of S_IRUGO.
* remove S_IFREG from mode.
* remove mode variable.
