4412开发板设置外部中断为下降沿触发，但是在上升沿的时候也触发中断

设置和问题如下：
1. 中断信号经过硬件消斗处理；
1. 调试迅为4412的外部中断时，设置中断为下降沿触发，但是在上升沿的时候也触发了中断，这里上升沿触发中断时，中断脚的电平读出来为 0；
2. 设置的外部中断脚为EXYNOS4_GPX2(0)，EXYNOS4_GPX2(1)，EXYNOS4_GPX1(2)，EXYNOS4_GPX3(0))，EXYNOS4_GPX3(2)；
3. 其中引脚EXYNOS4_GPX3(0)设置为下降沿中断时，在上升沿不会像其他引脚一样触发中断；
4. 设置为上升沿触发中断时，在上升沿会触发两次中断，在第一次中断时，读取中断脚的电平为 0，在第二次中断时，读取中断脚的电平为 1 ；
5. 调试过程中没有加载下列make menuconfig 路径中提供的的任何驱动：
Device Drivers  --->                                                              
         Input device support  --->
                           

·     Keyboards  --->  
6. 中断配置代码如下：
