Yi Li	0d152c27e3	Blackfin: SMP: make core timers per-cpu clock events for HRT ... SMP systems require per-cpu local clock event devices in order to enable HRT support. One a BF561, we can use local core timer for this purpose. Originally, there was one global core-timer clock event device set up for core A. To accomplish this feat, we need to split the gptimer0/core timer logic so that each is a standalone clock event. There is no requirement that we only have one clock event source anyways. Once we have this, we just define per-cpu clock event devices for each local core timer.

Graf Yang	1fa9be72b5	Blackfin: add support for gptimer0 as a tick source ... For systems where the core cycles are not a usable tick source (like SMP or cycles gets updated), enable gptimer0 as an alternative.
