From: Dennis Gilmore <dennis@ausil.us>

we attempt to autoload the module if it is defined in the dtb as the
default trigger. however none of the modules provide an alias of
"ledtrig:<default trigger>" change the : to a - so that the module is
picked up by its existing name. For example: ledtrig-heartbeat loads
while "ledtrig:heartbeat" is not found.
