You're right, but...

... which functions?  cpu_enable_ticks and cpu_disable_ticks call it,
but the result is only used by cpu_get_ticks.  As you said, this cannot
be called in icount mode.

A couple of PPC device models call it, but they probably should call
cpu_get_ticks instead.  So it looks like handling REAL_TICKS is
altogether unnecessary.
