ACPI: thinkpad-acpi: cleanup hotkey_notify and HKEY log messages
Use a generic message on hotkey_notify to log unknown and unhandled events,
and cleanup hotkey_notify a little.
Also, document event 0x5010 (brightness changed notification) and do not
log it as an unknown event (even if we do not use it for anything right
now).
