Changhwan Youn 0c0f909689 ARM: S5PV310: Optimize interrupt source searching code
It is reported by Junseok Jung that using clz instruction is
better instead of using for-loop to find the interrupt source.
This patch modifies interrupt source searching code using __ffs().
The __ffs() is implemented using clz instruction.
