AceLan Kao 5dd760b813 dell: add new dell WMI format for the AIO machines
There is a new DELL WMI spec. with new WMI event format.
I'm working on the AIO machines, but I think the new format will apply to
all the Dell's machines, not only for AIO, which will be released later
this year.

The new format of the WMI buffer is shown as below
word 0 - the number of words following in the WMI buffer(not including
        this word.
word 1 - the event type
	0x0000 - A hot key is pressed or an event occurred
	0x000F - A sequence of hot keys are pressed
word 2 and on - the event data

Colin Ian King 820787fceb Enable Dell All-In-One volume up/down keys
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.
