ACPI: thinkpad-acpi: fix sysfs paths in documentation

The documentation used "thinkpad-acpi" to refer to the directories in
sysfs, while it should have been using "thinkpad_acpi".  Thanks to Hugh
Dickins for the error report.

I wish I could just call the module and everything else by the proper
name with the "-", instead of using these ugly translations to "_".
