[PATCH] sim: rx: replace cycle-stats with common profile settings

[PATCH] sim: rx: replace cycle-stats with common profile settings

[Mike Frysinger]

The common sim-profile option controls whether to keep track of
runtime execution (like cycle count), so switch the rx-specific
cycle-stats option over to that.
