I think whether we force everything to have a power_save() function,
even if it is empty, or initialize a pointer and have an indirect call
doesn't make much difference.  What does make a difference, is there could
be power save functions that are unique to a board.  Some processors have
power save options that can cause a lower frequency clock to be used which
will affect external devices.  In such cases, the devices on a board may
need some adjustment when these power save modes are entered/exited.
