[hpsdr] Demeter: Some calculations

[Chris Albertson]

You can't assume people will have only one of each type
board plugged into Atlas.  Some people might want
to have multiples of the same board.  I think the way to
go is to look at the buss itself and assume a worst case.
Also we don't know anything about future developments.  
Design the PS assuming that each card has maxed out it
power budget.  Even with a worst case like this, it's still
only a few amps
