Document more clearly that a probe routine:
	Should have no side effects
	Must not hold resources when it returns
	May be called multiple times if it returns < 0.

Remove the bad advise that the probe routine should look for children
for devices that implement busses.  This is more properly reserved for
the attach routine.
