[board/common] automatically choose default (release) LM32 software file

instead of declaring in many places the path to the binary with LM32 software, simply say everywhere "default_altera" or "default_xilinx" and depending on PCS/simulation settings, pick the proper file at the board (common) level.

instead of declaring in many places the path to the binary with LM32 software, simply say everywhere "default_altera" or "default_xilinx" and depending on PCS/simulation settings, pick the proper file at the board (common) level.
