config patch

It seems like amdgpu strongly requires access to debugfs and panics when
CONFIG_DEBUG_FS_ALLOW_NONE is set. Also there is no debugfs-related flag for
amdgpu - it seems or amdgpu should depend on CONFIG_DEBUG_FS_ALLOW_ALL, or it
should have separate debugfs flag to enable/disable debugfs usage (it is seems
very possible as it was working early w/o access to debugfs).
