This creates "ufs" directory in the root of debugfs. So if there are
two or more UFS host controllers on a single system, only the first
one can succeed. Should we append the index for unique directory
name for each contoroller like "ufs0", "ufs1", ...?
MMC debugfs support does something similar, it creates "mmc0"
directory in the root of debugfs.
