From: Matthew Garrett <mjg59@xxxxxxxxxxxxx>
The kernel has a set of blacklist entries that disable ACPI functionality
on various machines. These all seem to date from pre-git days and most
have no indication of what they were meant to fix. Let's work on the
assumption that we've fixed whatever it was that was broken before and so
remove most of the entries.
