All of the architectures except PowerPC seem to have a indirect
pointer to a power saving idle function from the idle loop. If
you don't want to follow this, we could have all of the board
specific files contain a 'power_save()' function, which could be
empty, always compile it and always call it. Today, the power
saving stuff is all 6xx/7xx/Mac specific, which kinda needs to
change if we want address the needs of embedded processors and
products.
