sched: reintroduce SMP tunings again

Yanmin Zhang reported an aim7 regression and bisected it down to:

 |  commit 2db3703edecdf0f58d7cfe79f85adf7215c0e14a

 |
 |     sched: uniform tunings
 |
 |     use the same defaults on both UP and SMP.

fix this by reintroducing similar SMP tunings again. This resolves
the regression.

(also update the comments to match the ilog2(nr_cpus) tuning effect)
