Enable Dell All-In-One volume up/down keys

Browse Source 
Enable volume up and down hotkeys on WMI events
GUID 284A0E6B-380E-472A-921F-E52786257FB4 and
GUID 02314822-307C-4F66-bf0E-48AEAEB26CC8.

Also works around a firmware bug where the _WED method
should return an integer containing the key code and in fact
the method returns the key code in element zero of a buffer.
