tests/psr: Avoid opening of already open debugfs dir

The tests calls igt_debugfs_dir() to open the debugfs dir and further
along calls igt_debugfs_read() each time i915_edp_psr_status needs to be
read. As igt_debugfs_read() opens the directory unnecessarily, switch to
using the newly added igt_debugfs_simple_read()
