CCS-COMM_BOARD/DSP28335
Oleg 46d4b79e90 Add modbus.
Init with CPU data. If COMM is removed and then installed back -
modbus will not work because CPU board will not send config data.
CPU board should detect reinstalling/reprogramming of COMM board and
send config data again (with asking software version)

Modbus here just work itself. There is no connection btw COMM and CPU
except sending config data
