[PATCH v2 5/8] drm/amdgpu: Refactor sysfs removal

[Andrey Grodzovsky]

Hi, back to this after a long context switch for some higher priority stuff.

So here I was able eventually to drop all this code and this change here 
https://cgit.freedesktop.org/~agrodzov/linux/commit/?h=amd-staging-drm-next-device-unplug&id=61852c8a59b4dd89d637693552c73175b9f2ccd6
was enough for me. Seems like while device_remove_file can handle the use case 
where the file and the parent directory already gone, sysfs_remove_group goes 
down in flames in that case
due to kobj->sd being unset on device removal.
