sched/smp: Make SMP unconditional
Simplify the scheduler by making CONFIG_SMP=y primitives and data
structures unconditional.
Introduce transitory wrappers for functionality not yet converted to SMP.
Note that this patch is pretty large, because there's no clear separation
between various aspects of the SMP scheduler, it's basically a huge block
of #ifdef CONFIG_SMP. A fair amount of it has to be switched on for it to
boot and work on UP systems.
