lib/debugfs: Function to read debugfs with the directory already open
tests/kms_frontbuffer_tracking and tests/kms_psr read debugfs nodes
several times after opening the directory once. There is already an
implementation of this in the kms_frontbuffer_tracking, moving that
functionality to the library will allow us to share the code with kms_psr
and kms_fbcon_fbt
