[En-Nut-Discussion] Bunch of Harmful Modifications in CVS

no big deal. Looks like Harald did put the platform specific code of 
irqreg.h into various irqreq_{PLATFORM}.h files
but omitted to do the same with the unix code. (or whatever..)

For now, just comment the line #warning "MCU not defined" in 
nut/include/dev/irqreg.h and everything
is back working. I'll properly fix it in CVS soon (also putting the 
unix code into, let say, irqreq_unix.h ..) :)
