sched: Implement generic sleep mechanism based on tasks pending
Track when tasks are pending and spin in irq_wait() when no tasks are
pending. This improves the mechanism for sleeping the processor -
it's simpler for the board specific code and it reduces the
possibility of the processor sleeping when tasks are busy.
