PEL: LightPath: Assert LED groups
Fill in the functions to get the LED group D-Bus paths corresponding to
the called out location codes, and then set the Asserted property on
that path to turn on the LEDs.
If there are any problems looking up any of the LED groups, then do not
turn on any LEDs at all, even if others were OK. In this case, the
system attention indicator will be turned on instead.
