The advanced fault logging has been removed from the specification since
v4.0. Linux doesn't implement advanced fault logging functionality, but
it currently dumps the advanced logging registers through debugfs. Remove
the dumping of these advanced fault logging registers through debugfs to
avoid potential access to non-present registers.
