The commit
4cec16861a40 ("PCI/ASPM: Convert to use match_string() helper")
didn't take into consideration small but crucial detail about scope of
usage, i.e. sysfs interface provided to handle the ASPM policy. Due to
this in most of the cases input string comes with a new line symbol.
Use sysfs_match_string() helper to take into account above.
