make LED definitions board specific

Browse Source 
the LEDs (2 of them) were connected to the same pins on all
boards, up to the octsim-tester.
to be able to have board specific LEDs the definitions have moved
from common to the each board.
at the same time I added a bit of documentation what the LEDs are
used for.
